Almost unthinkingly Saffron follows and finds herself in a whole new world. This strange woman, Gwen, is originally from Earth but years ago became a worldwalker and made this world and its country of Kena her home.
Kena is in the midst of political turmoil. To Gwen’s eternal regret, she supported a candidate for the thorne who turned out to be a backstabbing tyrant. Now Gwen and the group of rebels she belongs to have laid their sights on forming an alliance with the neighboring country of Veksh, whose government is rife with its own set of tensions and factions. Immediately thrust into a bewildering landscape of magic, politics, and religion, Saffron comes to play an integral role in determining Kena’s future. But at what cost? And what price will she have to pay upon the day she returns home?
