Desperate to break out of the anachronistic community where she has grown up, Poppy determines to save the planet her way, but naivety means she becomes inextricably tangled in the confusing espionage of Caernef. She idolises the enigmatic Miranda, who pays scant attention to her young admirer. By 2034, Nathan, tech-genius of the previous books, has become a multi-billionaire through his Virtuality cyber games. He creates Pia, Poppy's digital twin, unethically, using AI. Poppy is incandescent. As the Caernef gang, led by Robin, reconvenes, Poppy is caught between Miranda and Robin's competing versions of #FutureProof. Virtuality and reality collide in the Future Galactic programme. The future of the planet depends upon the unique fingerprints of both Poppy and Pia.
