Picking up where Edge of Time left off, Time of Treason continues the story of Riley and Alec, otherwise normal teens whose special genetic traits grant them powers they are only now learning to control – powers that also make them targets for the extraterrestrial Tyons. Riley and Alec travel back in time to the start of their adventures, courtesy of Alec’s creepy time shifting abilities. But instead of fixing things, it’s made everything much worse. The Tyons tracked their time shift and are hot on their heels, and Rhozan is back, more dangerous than ever. After a brazen attack, Alec finds himself out of the frying pan and definitely into the fire. Can Riley save him? Or is Alec just a pawn of time?
