Sign in to your ScreenRant account Threshing Day is already shaping up to be one of the biggest fantasy releases of September, but Rebecca Yarros' tightly controlled rollout of the Fourth Wing release has suffered an unexpected setback. The new Empyrean novella is scheduled to hit shelves on September 29, 2026, and only days after Rebecca Yarros publicly asked fans and retailers to protect its surprises, an unauthorized audio clip appeared on Spotify. The timing makes the situation especially frustrating. Rebecca Yarros had previously explained that she wanted Threshing Day to arrive as a complete surprise with no prior marketing or anticipation, partly because Onyx Storm suffered major pre-release spoilers back in 2025. Now, with the new book less than three weeks from publication, fans have once again had material placed online before they were supposed to hear it. Spotify Accidentally Released Part Of Threshing Day's Audiobook According to a moderator announcement on the Fourth Wing subreddit, Spotify uploaded an unauthorized audiobook clip from Threshing Day. The subreddit identified the material as a leak and immediately began removing posts that shared or discussed what was heard. The moderators also confirmed that Rebecca Yarros herself had said the clip was released without her approval. The leak was especially confusing because it happened on the same day as the A Court of Splintered Harmony leak, and it was released on the official Spotify page associated with the audiobook. That meant some fans reasonably assumed the sample had been intentionally released as part of the marketing campaign. Reddit users described hearing roughly two minutes of material, while others referenced longer versions circulating elsewhere after the original appearance. Spotify eventually removed the sample, but the damage was already done. Screenshots, recordings and discussions had begun spreading across social media, creating exactly the kind of spoiler problem Rebecca Yarros had tried to prevent. The situation also highlights how difficult it is for fans to distinguish an unauthorized leak from legitimate promotional content when it appears through an official platform. The Threshing Day Leak Comes Days After Yarros' Warning The timing is almost painfully ironic because Yarros had just asked Fourth Wing fans not to spoil Threshing Day before release. In her plea, she specifically addressed retail workers who might encounter copies early, explaining that she wanted the novella to arrive without the extensive pre-release exposure that affected Onyx Storm. Rebecca Yarros' concern was understandable given how much mystery surrounds the novella. Threshing Day will revisit the pivotal dragon-bonding event through the experiences of 13 characters from the Empyrean series, potentially revealing new dragons, character histories and details that could influence the larger story. With Book 4 still in progress, even seemingly small revelations could fuel enormous fan speculation. That makes the Spotify incident more consequential than a routine audiobook preview appearing too early. Fourth Wing fans have spent months waiting to discover which characters receive their own Threshing Day stories, and the September 29 release is supposed to provide those answers officially. For readers committed to going in blind, the leak is an unwelcome interruption just as Rebecca Yarros was trying to preserve the surprise.
