Shadow and Bone has been cancelled, one of five series that will no longer be going forward for more seasons, Netflix has announced. Deadline reports that this is due not only to series’ performance vs. cost, but also to the delays in writing and filming caused by the WGA and SAG-AFTRA strikes.

Shadow and Bone, which hails from creator, writer and executive producer Eric Heisserer and is inspired by the bestselling Grishaverse novels by Leigh Bardugo, aired for two seasons. Set in a war-torn world of magic, the series follows First Army cartographer and orphan Alina Starkov, as she discovers an extraordinary power that could be the key to freeing and uniting the Ravka nation. Jessie Mei Li stars as Alina, along with Archie Renaux, Freddy Carter, Amita Suman, Kit Young, and Ben Barnes.

In an Instagram post, Bardugo wrote that she was “heartbroken and deeply disappointed” after learning that Shadow and Bone had been cancelled and would not receive a Season 3, nor would a Six of Crows spinoff be going ahead (also set within the Grishaverse). However, she goes on to say that “I’m also trying to hold on to my very real gratitude. Most authors never get to see their work adapted. Many who do end up regretting the experience. I’m one of the very few who can look at an adaptation with pride and tremendous joy. I am so grateful to our writers, our crew and our extraordinary cast who are not just wildly talented, but genuinely good people.”

The other series no longer going forward at Netflix are Glamorous, Agent Elvis, Farzar, and Captain Fall.
