As Prophecies in the Book of the Wars Unfold, the Only Hope Is Uniting with the Enemy.

Leif Metcalfe is done waiting for answers and seizes control, a move that comes with a high price and a deadly risk: teaming up with the enemy. He can only pray what he uncovers will heal the wounds he's inflicted on those he loves.

Iskra Todorova refuses to believe Leif is irrevocably lost, despite evidence to the contrary. While trying to protect her daughter and track down Leif before it's too late, Iskra wonders if a member of the evil organization ArC has been in their midst since the beginning.

Torn apart by injuries and opposing views about Leif's treachery, team Reaper hunts one of their own. The only thing they agree on is not stopping but starting the final battle prophesied in the Book of the Wars.
