THREE MILLION SERIES COPIES SOLD! The highly anticipated fourth novel in the #1 New York Times bestselling Lightlark Saga, by acclaimed author and #BookTok sensation Alex Aster   Some worlds deserve to be destroyed . . .   Isla Crown has charted a new destiny and leapt into the unknown, determined to defeat her insidious ancestor, Lark, no matter the cost. But Skyshade is nothing like she anticipated, and she’ll have to use all of her skills just to survive, let alone end Lark for good.   Meanwhile, Grim and Oro would sooner set fire to their own kingdoms than leave Isla stranded on a path toward certain death. But getting her back will involve forging an alliance—if they can find a way to forgive their long history of betrayals.   The key to Isla’s return—and the fate of the realms—lies close to her heart. But in the face of her most powerful enemy yet, will Isla be able to reconcile her past in order to carve a future of her own making? Filled with secrets, deception, romance, and twists worthy of the darkest thrillers, The Lightlark Saga is a must-read for fans of legendary fantasy writers Marie Lu, Marissa Meyer, and Leigh Bardugo.
