Rain is the perfect killing machine. She lacks emotion and is superhuman in almost every way. Me? I'm just Cassie, tagging along for the ride. I'm a normal person caught up in Rain's plan to free everyone on Earth from the clutches of World Corp. You'd think we'd be welcomed as heroes. Not so much. No one knows that World Corp has complete control over them... nor do they know about the rebellion that's starting. And let's face it... they're better off not knowing.
