For months Summer is trapped in a cellar with the man who took her - and three other girls: Rose, Poppy, and Violet. His perfect, pure flowers. His family. But flowers can't survive long cut off from the sun, and time is running out...

Sixteen-year-old Sage Greene was locked in a maximum-security asylum for the criminally insane after murdering nearly 200 civilians. It isn't her, though - it's the voices. There are two sides to Sage: the normal, self-conscious teenager, and the Voice lurking inside her head, the one that forced her to strike out and kill. Now, both parts of Sage are being sent into space, destined for a new rehabilitation program upon Mars, with a group of the most dangerous teenagers in America. Before they can reach the red planet, however, they are abducted by a strange alien race and taken away from their spaceship and everything they have ever known to compete in a sadistic set of physical and mental tests nicknamed the Trials. And so far, nobody has survived the Trials. * {Highest ranking: #5 in science fiction as of 9/3/17} [Comment threads contain spoilers at random.
