Squee! I adored this book. Karen's two previous books were fantasy, and I liked them a whole lot. But this, her first published science fiction novel, is even better. This is an adventure story set in an Australia 115 years in our future, a world of spiralling climate change, legislated xenophobia, and layer upon layer of conspiracy. Tegan is a idealistic teenager from 2027 with a brand new boyfriend, a climate change protest to go to, and a thing for the Beatles. Suddenly, she has to deal with not only piecing her life back together when she is unfrozen from cryosleep one hundred years later, but with finding herself at the centre of a maelstrom of lies, manipulation, and media frenzy in a future world that is not at all the better place she had hoped it would be. I loved the way that issues of today are carried forward into this book (whether things have improved or ...not) without it being overly preachy, and the way in which the book poses questions about the sorts of ethical and legal issues that could arise if waking from cryosleep ever became technically possible.The pacing is terrific, with the the plots and secrets revealed in a way that is alllmost horrifying enough. The world-building is believable and palpable and the characters are varied and immediately engaging. I closed this book wishing desperately that there was a sequel so that I could re-immerse myself into this world.
