A post-apocalyptic literary epic in the tradition of The Handmaid's Tale, Divergent and Cloud Atlas, and a breakout book in North America for a writer of rare and unconventional talent. From Guardian First Book Award finalist Sandra Newman comes an ambitious and extraordinary novel of a future in which bands of children and teens survive on the detritus--physical and cultural--of a collapsed America. When her brother is struck down by Posies--a contagion that has killed everyone by their late teens for generations--fifteen-year-old Ice Cream Star pursues the rumour of a cure and sets out on a quest to save him, her tribe and what's left of their future. Along the way she faces broken hearts and family tragedy, mortal danger and all-out war--and much growing up for the girl who may have led herself and everyone she loves to their doom.
