Riven — Sherry Ficklin; Tyler Jolley

What should be a routine mission leaves Ethan with a serious problem. He's fractured―a break between mind and body that leaves him at the mercy of his Rifter abilities, which are quickly tearing him apart. He will have to trust the only person who might know how to fix him, a mysterious Rifter named Stewart Stills, who seems to have a special connection with the time stream.

Forced to face his dark past and a decision he may never forgive himself for, he will be trained unlike any of the others, to become a true guardian for time. If he accepts, it will mean leaving everyone he loves behind. If he refuses, time itself could unravel. After a glimpse of the dark future awaiting them all, he will have to choose between destiny and desire. Will he rise up and take his place as a defender of the natural order, or will he watch as all of time burns at the hands of the girl he loves?

Welcome to the time war.

In a battle for control of the time stream, the past and the future will collide, either saving mankind―or destroying it.

The Tesla Institute stands on one side of the battle. Controlled by the mind of one of the greatest inventors in history, the Institute recruits gifted, young time travelers called Rifters. Those who survive his training are sent into history with the mission to preserve the time stream, recruit more of their kind, and better humanity through subtle, controlled event manipulation.

Standing in the way are the Hollows, a rogue group of Rifters who have vowed to put an end to the Tesla Institute―at all costs. They steal, cheat, and bend history to their own ends. Using children stolen from time as their personal armies, they fight not only for control of time itself, but also for self-preservation.
