Queen of Shadows follows Celaena Sardothien, a complicated female assassin with a mysterious past who only wants her freedom. Now beholden to an increasingly tyrannous king, Celaena will become a reluctant hero against the multitudes of forces that threaten to destroy her world. Along the way she will make friends, enemies, and lovers, and be wildly underestimated by all of them.

The Mark Gordon Co’s Mark Gordon and Nick Pepper will executive produce with Snyder and Foerster.
