From the author of Here There Are Monsters comes a chilling supernatural horror that is part terrifying vampire legend and part modern exploration of toxic relationships wrapped up in a novel about hunger, yearning, and loss.

After the sudden death of her perfect, popular older sister, Jo and her family feel empty. But days after crying at Audrey's graveside, Jo stumbles on the impossible: Audrey, standing barefoot in the snowy backyard. But Audrey isn't breathing. She's still marred with the evidence of an autopsy. She's decaying. And worst of all, Audrey is hungry, and only human blood can curb her relentless appetite.

Jo knows she can put her family back together; she just has to figure out how to fix Audrey. She hides her sister and sustains her with her own blood, determined to figure out how to keep Audrey with them. When her search takes her to her sister's grieving inner circle of friends, Jo finds herself drawn into their fold—and to Audrey's boyfriend, Sam.

As Jo slips further into her sister's old life, Audrey's hunger and jealousy grow more insatiable. She's not going to sit back and let Jo replace her or, worse, discover the secrets hidden beneath her golden girl facade. As Jo struggles to juggle everything she will be forced to decide which of her loved ones needs her the most and who she's willing to sacrifice to save them.
