Janci Patterson and Brandon Sanderson Launch Sci-Fi Trilogy

Author Janci Patterson and fantasy titan Brandon Sanderson are officially launching a new full-length science fiction trilogy set within Sanderson’s popular Cytoverse. The opening instalment, titled Blightfall, arrives on Tuesday 2 September 2026, marking a major milestone in a collaborative partnership that began several years ago.

The new trilogy, reported under the series heading Riftwake, expands the universe originally established in Sanderson’s Skyward series. While the pair previously collaborated on a suite of companion novellas to flesh out the expanding setting, Blightfall represents their first full-length novel written together in this shared fictional universe.

Expanding the Cytoverse

The collaboration between Patterson and Sanderson has evolved naturally over the past few years. Sanderson first approached Patterson several years ago to ask whether she would be interested in writing novellas set in his sci-fi universe. That initial project proved successful, laying the structural ground for a deeper creative partnership.

For Patterson, taking on a complete sci-fi trilogy marks an exciting shift in focus. “Right now, I’m in my science fiction era,” Patterson said, reflecting on her move into co-writing large-scale space opera alongside one of modern fantasy’s most prolific figures.

The publishing schedule for the series is structured to keep momentum steady for readers. Patterson explained that the plan is for “each book to be released a year apart from each other.” Following Blightfall, the second book in the trilogy, titled Songrise, is currently on track for release in September 2027.

Co-Writing at Scale

Shared-world writing and high-profile co-authoring arrangements have become increasingly common in genre publishing, but Sanderson’s approach to bringing in co-authors on his intellectual properties has been notably structured. Rather than simply licensing out the setting, Sanderson worked closely with Patterson during the novella stage before committing to a mainline trilogy of novels.

Some early reports and retail listings have occasionally referred to the project under alternative sub-series branding, including the Skyward Flight banner, reflecting how publishers manage universe branding across sprawling franchises. Regardless of the precise series label on the cover, the narrative directly continues the broader Cytoverse trajectory following the events of the original books.

If you have been keeping an eye on the broader landscape of speculative fiction this year, it has been a busy season for genre announcements. From recent honours like the 2026 Arthur C Clarke Award announcement to major seasonal line-ups across traditional publishing houses, science fiction readers are currently spoilt for choice. As part of the key autumn book releases arriving on shelves this month, Blightfall aims to capture both long-time fans of Sanderson’s Cosmere and Cytoverse works as well as readers drawn in by Patterson’s fast-paced narrative style.

What Comes Next for the Series

With Blightfall hitting shelves this week, work on the subsequent volumes is already well underway. The predictable annual release cadence championed by Patterson and Sanderson offers a structured runway that readers of big genre series rarely get to enjoy these days.

For readers diving into the new book, Blightfall serves as both a direct continuation for existing Cytoverse devotees and a fresh jumping-on point for those who caught up through the earlier novellas. With Songrise slated for autumn 2027 and a third unannounced title expected in 2028, Patterson’s sci-fi era looks set to keep her very busy for the foreseeable future.
