Fifteen-year-old Tobias Doljan Walked back in time to prevent a war, but he instead found himself trapped in an adult body, with his king murdered and with an infant princess, Sofya, to protect. Now he’s been joined by fellow Walker and Spanner Mara, and, together, they must find a way to undo the timeline that orphaned the princess and destroyed their future. Arrayed against them are assassins who share their time-traveling powers but have dark ambitions of their own, and the Tirribin demon Droë, whose desperate quest for human love and Tobias leads her into alliances that threaten all of Islevale.
