Jessica Khoury's first novel Origin had a shadowy biotech company genetically engineering immortality and the teenager who was the result of the research. Her new novel, Vitro, published by Razorbill/Penguin, has a different cast of characters, but the same company is manipulating humanity itself for their own ends. 17-year-old Sophie Crue returns to the South Pacific to search for her estranged mother and discovers the truth about the research facility where her mother has been working.
