Jessamine Baxter has grown up in a peaceful society where parapsychs and non-parapsychs - widely known as 'laterals' - are treated equally, but when Jessa's own parapsych abilities begin to strengthen in unforeseen ways, she starts to suspect that parapsychs and laterals might be more different than anyone could have imagined.
As she grapples with the responsibility of her increasing power, Jessa's abilities lead her to discover mysterious activity within the parapsych world. She teams up with her best friends and a history teacher to investigate further, and when they unearth the identity of the perpetrator, they learn that his intentions could have utterly devastating consequences.
Ultimately, Jessa and her friends are left with only one option - to bring down their new and dangerous adversary. If they can, a great tragedy will be prevented. If they can't, the age-old peace between parapsychs and laterals will swiftly unravel.
