Nix Loring stepped into Mystiquel to face the Goblin King and break her family's curse. When she found her twin, Lark, held captive for three years and forced to power the magical realm with her imagination, Nix offered herself up in her sister's place. Now, Nix wants nothing more than to be home with the people she loves. Instead, she's tasked to create beauty from a world fallen to desolation. She finds herself drawn to the faerie creatures under her care-and even reluctantly drawn to the Goblin King himself. But how can she rebuild the very realm that tore her family apart? Back home, her uncle and boyfriend desperately plan a rescue. But Lark, having learned Nix was meant to be the Goblin King's captive in the first place, resents how her twin stole everything belonging to her during her absence. Worse yet, Lark harbors an unspeakable secret that could destroy what little she has left. As time draws closer to the rescue, Lark grapples with the darkness growing inside: should she help save her sister, or finally get her revenge? Set in a gritty, atmospheric world filled with magical creatures, New York Times bestselling author A.G. Howard concludes her thrilling fantasy duology full of romance, twists, and betrayals.
