Regret. Loneliness. Despair. Alina struggles with these feelings every night. Centuries ago, her kind was all but wiped out by a mysterious disease that left them unable to produce the venom needed to make new vampires. She's the last one - isolated in what feels like a never-ending nightmare.
But she discovers a homeless man named Terrence who's in the early stages of becoming a vampire. He doesn't remember how he got turned. That doesn't matter to Alina because if he feeds, he'll complete his transformation and have the power to save her race from extinction.
Alina offers to teach him vampire culture and history. Longing to find a place where he belongs, Terrence accepts. But he's appalled at the idea of living on human blood, so he refuses to feed. Alina resorts to manipulation and deceit to try and get what she wants.
Meanwhile, Alina's past closes in on both of them as an immortal named Lanier hunts her to avenge the murder of his brother. And he's been ordered by a mysterious figure named Duke to find a special book thought to be in Alina's possession. But what's in this book? Why is it so important?
If Alina can save her race, she'll find her redemption. But can she persuade Terrance to do the unthinkable...before it's too late?
