Old secrets come to the surface, friendships are forged and betrayals discovered, and a girl, Alendra, has managed to take hold of Elei's feelings.With a map that leads underground and the hope of toppling the Gultur regime, Elei and his companions seek a weapon to tip the balance of power. But unrest within the resistance means that this time they are on their own and, as if crossing a world torn by war while keeping Rex under control wasn't enough, Elei fears that before the end Alendra might break his heart.
