Young Adult Literature; Horror
Why YA? We're so glad you asked. Even though Nina's been a vampire for, like, decades, she was fifteen when she was infected, and she still looks—and acts—a lot like a teenager. She rolls her eyes, she's sarcastic on the regular, and she crushes on teenage guys (Dave was infected while a teenager, and Reuben still is one).
Like in other young adult novels, the plot revolves around Nina gaining independence, solving problems, and connecting with her love interest. But there are also elements of horror here, though they're on the low-key side rather than the gut-churningly gory side.
There are definitely moments of scary suspense, like when the gang first stumbles upon Casimir's remains, and nobody knows if the killer's still in the apartment. Nina remembers "how my gut seemed to drop through the floor. I remember thinking: Is the killer in that wardrobe? If not, where is he? In the neighboring flat? In a car downstairs? What if he's outside, waiting for us?" (3.29) Dun dun dun…
Yep, that's some freaky stuff. Add in the subject matter—vampires and werewolves—and we are definitely in the land of horror.
