How much is one life worth and what would you sacrifice to save it? For Calico, the answer is simple. Nothing is more important than preserving her sister's life. No cost is too great. Until it is . . . Saving Asha. That's my religion. That's my science . . . Without Asha, there is no me. Asha is dead. Years of medical treatment were not enough to heal her. The only way 17-year-old Calico can save her younger sister now is by joining her in death - at least until modern medicine can bring them both back to healthy life. Cryogenics is the answer: Scientific. Legal. Safe. Or so Dr Fates would have her believe. He plans to preserve the sisters' bodies until his biotechnology research finds a cure for Asha. But when Calico is brought back to life, she's in a post climate catastrophe, low-tech future trapped in a research facility. She's at risk of being sold off to a sinister enforced breeding programme. And worst of all - Asha is missing. Calico must find a way to save her sister, herself, and the new friends she's made among the other test subjects. But first she has to unravel the secrets the facility is hiding and reveal the lies she has been part of. In this striking debut, Kathryn Clark raises poignant questions about the ethics of medical science, humans playing god, the consequences of our choices, and the place of consent in healthcare.

The story of a world that is beginning to fall apart, and a chance to see it all put back together, The Raven’s Song is a vision of hope for the future, seen through the eyes of the young people who will fight for it.
