A teenage shape-shifter called Eo.
A boy from the 6th century called Adom.
And a girl from the 24th century called Jay.
What do they have in common? More than you can possibly imagine. Because one careless mistake by Eo has led to a time-travelling challenge that could cost them their lives.
And now they're being hurled back and forth through time in a game which there can only be one winner.
Beautiful, soul-sucking demons will ravage Eo's world if they fail. But Eo, Adom and Jay are ready to face whatever the seven tides throw at them.
