Three years ago, Damian Blackwood buried his wife. Tonight, she walked through his balcony door wearing her own wedding ring — and she has no idea who he is. She calls herself Luna. She says she's never met him. But she remembers his voice. She remembers dying. And she remembers a promise he made at her grave that no living person heard. Someone wanted Seraphina gone. Someone in Damian's own family knows why. And the more Luna remembers, the more determined that someone becomes to make sure she never wakes up again. He buried his wife once. He won't survive burying her twice.
