10 Near-Perfect Book Trilogies That Everyone Must Read at Least Once

Published Sep 9, 2026, 3:19 PM EDT Diego Pineda has been a devout storyteller his whole life. He has self-published a fantasy novel and a book of short stories, and is actively working on publishing his second novel. A lifelong fan of watching movies and talking about them endlessly, he writes reviews and analyses on his Instagram page dedicated to cinema, and occasionally on his blog. His favorite filmmakers are Andrei Tarkovsky and Charlie Chaplin. He loves modern Mexican cinema and thinks it's tragically underappreciated. Other interests of Diego's include reading, gaming, roller coasters, writing reviews on his Letterboxd account (username: DPP_reviews), and going down rabbit holes of whatever topic he's interested in at any given point. For someone who loves reading, there's nothing quite like finding an incredible trilogy to sink one's teeth into. It's usually a considerable time commitment, but the trilogies that are worth such dedication always find ways to reward readers' patience in all sorts of ways. It's a wholly different thing, though—one far rarer and, for obvious reasons, even more precious—to find a book trilogy that's not only great, but almost downright perfect. The keyword here is "almost." While there are a few book trilogies out there that could be argued to be perfect from start to finish, there are others that are near-perfect and still essential reading. From Louisa May Alcott's Little Women books to Stephen King's Bill Hodges series, these are book trilogies that approach perfection, despite having a few substantial flaws here or there, ranked in order of how close they get to true flawlessness. For that reason, anyone who loves reading should check them out at least once in their lives. The Gormenghast Trilogy Image via The Overlook Press Mervyn Peake first earned his reputation as an exceptionally important British artist through painting and illustrations, but it would be his visionary Gormenghast Trilogy that would end up being the most defining chapter of his career. This genre-bending Gothic masterpiece is so gleefully subversive that it almost entirely rejects any kind of label or categorization, even though most people tend to consider it a landmark title of Gothic fantasy. The core trilogy is composed of Titus Groan, Gormenghast, and Titus Alone, which are accompanied by the novella Boy in Darkness. These are powerfully slow, claustrophobic, and satirical books full of richly detailed worldbuilding. By the time he wrote Titus Alone, however, Peake was already beginning to succumb to the early stages of the Parkinson's-related dementia that would eventually claim his life (leading to the fourth book in what was originally meant to be an expansive series, Titus Awakes, to be completed by his widow, Maeve Gilmore). As a result, this ends up being a tragically flawed and uneven conclusion to what otherwise would have been a faultless trilogy. The Little Women Trilogy Image via Puffin Books Louisa May Alcott was a towering figure in 19th-century American literature and social reform, an author whose challenging of traditional gender roles altogether transformed children's literature. From that subversion of societal conventions came Little Women, one of the best books that are over 100 years old. But though its publisher wanted the novel to be primarily aimed at young girls, Alcott imbued Little Women with such universal depth and appeal that anyone—regardless of their age or gender—should consider it a must-read classic. The book, originally published in two volumes, was so successful that Alcott penned two sequels: Little Men two years after concluding Little Women, and Jo's Boys 15 years after that. With the focus shifting away from the March sisters, however, the timeless charm that made Little Women a generational masterpiece faded. These sequels, however prone to Victorian moralizing and preachiness they may be, are nevertheless powerfully progressive and very much worth reading. The Wolf Hall Trilogy Image via Henry Holt & Company Hilary Mantel's historical novel Wolf Hall is all-around one of the best books since 2000, and undoubtedly the best installment in the trilogy that carries its title. Also composed of Bring Up the Bodies and The Mirror and the Light, the series is a fictionalized biography of the rapid rise to power of British statesman and lawyer Thomas Cromwell in the court of King Henry VIII, which is why the trilogy is sometimes also called the Thomas Cromwell series. Mantel's prose is at times a bit awkward in its stylistic ambitions, but the trilogy is nevertheless a monumental achievement whose boldness in being so expansive and experimental is nothing if not admirable. But while Wolf Hall and Bring Up the Bodies are so incredible that they both won the Booker Prize, it's typically agreed that The Mirror and the Light is a rather flawed conclusion that at times threatens to collapse under the sheer weight of its narrative bloat. In spite of that, the whole trilogy is essential reading despite how daunting it may seem to the non-initiated in historical fiction. The Passage Trilogy Image via Anchor Canada Justin Cronin has only written six novels in his lifetime, and half of those belong to the exceptional Passage Trilogy. This piece of dystopian vampire horror and dark fantasy was a pop-cultural phenomenon and an instant critical hit, widely praised for how it elevated genres that are often looked down upon as "low-brow" with artistic and thematic depth. Praised by people of the caliber of Stephen King and compared by critics to the work of authors like Cormac McCarthy and even Homer, it really is one of the best speculative fiction trilogies of the past couple of decades. Indeed, Cronin proved with The Passage, The Twelve, and The City of Mirrors that vampire fiction can be imbued with beautiful, undeniably prestigious literary depth and artistry. But while all three books deserve to be called masterpieces, they all suffer from some key issues, from the jarring time jump of The Passage to the pacing issues of The Twelve to the bloated length of The City of Mirrors. Even still, anyone who loves fantasy horror should read this trilogy at least once. Underworld USA Trilogy Image via Alfred A. Knopf, Inc. Crime fiction writer and essayist James Ellroy is one of the most monumental figures in American literature of his generation, his work having helped elevate the crime genre into true metafictional postmodernity (even if Ellroy himself rejects the label of postmodernism). Those interested in his work may as well start with his magnum opus: the Underworld USA Trilogy, widely regarded as one of the greatest achievements in the history of English-language crime literature. From American Tabloid (one of the heaviest books of the 1990s) to The Cold Six Thousand to Blood's a Rover, the trilogy deconstructs the United States' national mythology in ways that are constantly surprising and consistently thought-provoking. Ellroy's signature staccato prose can get downright exhausting over an entire trilogy, but those willing to space out their reading of the Underworld USA Trilogy will likely end up finding it intoxicating. MaddAddam Trilogy Image via McClelland and Stewart Ltd. Canadian author Margaret Atwood is widely celebrated as a profoundly important and groundbreaking author, particularly for her game-changing dystopian masterpiece The Handmaid's Tale. There are plenty of other Atwood works which should be considered essential reading, though, including her exceptional MaddAddam Trilogy. It's one of the best book trilogies of the 21st century, a masterpiece of dystopian fiction that could have only possibly been constructed by a master of the genre of Atwood's caliber. It's technically an excellent sci-fi trilogy, but Atwood directly rejects that genre label, instead preferring to think of Oryx and Crake, The Year of the Flood, and MaddAddam as a speculative-fiction examination of a terrifying corporate dystopia. The final book in the series isn't quite as subversive as its predecessors, and its efforts to tie everything together can feel a bit disjointed, but the trilogy is phenomenal nonetheless. The Hunger Games Trilogy There aren't very many dystopian books better than the Hunger Games trilogy, the one that put Suzanne Collins on the map and single-handedly ignited the massive young adult dystopian boom of the early 2010s. Published right at the peak of YA's popularity (largely thanks to Twilight), 2008's The Hunger Games proved that young readers were craving these sorts of dark, high-stakes speculative fiction gems. But though it's aimed at teens, the trilogy as a whole is such a near-perfect masterpiece that anyone who loves dystopian fiction should read it at least once in their lives, regardless of their age. The near-perfection of The Hunger Games was followed by the equal near-perfection of Catching Fire, which only makes it all the more of a shame that Mockingjay mishandled the story's conclusion in such a way that it's impossible to say the trilogy is truly flawless. But in spite of a flawed final book, it's still a trilogy that absolutely revolutionized YA literature and dystopian fiction, and that makes it a must-read. Bill Hodges Trilogy Image via Hodder & Stoughton Stephen King has been one of the leading voices in modern speculative fiction for decades, best known for his work in the horror genre. He has dipped his toes into a myriad of other genres throughout his career, as demonstrated by the hard-boiled detective trilogy known as the Bill Hodges series. It's not exactly a career-defining trilogy for King, but it does mark a successful late-career pivot which further proved King really could write pretty much anything. It may very well be one of the best book trilogies of all time, composed of three of King's most essential novels: Mr. Mercedes, Finders Keepers, and End of Watch. The first book in the series is a practically faultless masterpiece, but Finders Keepers suffers a bit from "middle installment syndrome," and End of Watch takes the series in such dramatic supernatural directions that it ends up feeling like somewhat of an identity crisis. But even despite its flaws, the strengths of the Bill Hodges trilogy are so great that it's still a must-read series. Sprawl Trilogy Image via Ace Books There's no overstating the pop-cultural importance of William Gibson's Neuromancer, one of the greatest speculative fiction books ever written, a foundational pioneer in the cyberpunk subgenre. While its sequels, Count Zero and Mona Lisa Overdrive, may not often be nearly as universally praised, they're still a pair of phenomenal additions to a trilogy that's an absolute must-read for anyone who even slightly enjoys science fiction. Is the Sprawl Trilogy flawed? Certainly, even if merely because its second and third chapters aren't nearly as novel or perfectly written as Neuromancer. But we're still talking about three of the best sci-fi thriller books of all time, with some of the greatest worldbuilding and most engrossing prose the genre has ever seen. No matter its flaws, it's undoubtedly a must-read trilogy. Game, Set and Match Trilogy Image via Penguin Books Len Deighton's Bernard Samson series advertises itself as a trilogy of trilogies, and it's no exaggeration to call the whole series a towering achievement in Cold War spy fiction, one that continues to be celebrated for how it helped redefine the genre. The first trilogy in the series is arguably the best of the bunch: the Game, Set and Match Trilogy, where MI6 officer Bernard Samson discovers that his wife defected to the KGB and has to grapple with the effects of her betrayal. Composed of Berlin Game, Mexico Set, and London Match, all three among the greatest spy novels of the 1980s, the Game, Set and Match Trilogy is one that anyone who loves spy fiction should read sometime in their lives. The poorly paced Mexico Set suffers from a bit of a case of "middle installment syndrome," and those who prefer self-contained trilogies may find London Match unsatisfying. At the end of the day, these are still some of the best spy books of all time, forming a trilogy that's a gold standard for spy book series.
