Seventeen-year-old Justin's anemic blood is a blessing. Or a curse. It all depends on who you ask. To most of the immortal Vie, his blood is a scourge: untouchable and useless. To some Vie, his blood is a drug. To Justin, it’s something that gets him in a lot of trouble. Being poisoned by a Vie is just one example. His sister getting kidnapped is another. Whether it’s being coerced by a deluded cult leader, or negotiating with Alex—an Vie scientist addicted to Anemie blood—Justin struggles to keep every mutated drop of blood he’s got. His fight for survival gets more complicated when he meets Alex’s slave, Cara. Despite coming from different worlds, they’re both prisoners, at risk of being drained by a hungry Vie any moment. When she risks her own neck to help Justin find his sister, he's left with a terrifying choice. Saving what's left of humanity. Saving his sister. Saving the girl he loves. Or sticking a stake in Alex’s chest. Justin can't decide which option will get him killed first.
