What Cassie doesn't realise is that there's more at risk than a few unsolved murders - especially when she's sent to live with a group of teens whose gifts are as unusual as her own. Soon, it becomes clear that no one in the Naturals program is what they seem. And when a new killer strikes, danger looms close.
