Rise of the Alliance IV: Nightside of the Sun (Hardcover) (ISBN-13: 9781636320236)

The climax to the Rise of the Alliance saga begins with Detlev's boys taking two prisoners as they retreat to their lair on Five, the sister world that has been lifeless for nearly five thousand years. Reviled by both sides, the one thing they can trust is their strength, their training, and each other. Or so it seems.

Meanwhile, unknown to both Norsunder and the Sartoran mages, there are secrets within that world that will change everything.

The high-stakes hunt continues on two worlds as the surviving allies step into adult roles one by one, just to find themselves with greater challenges as the world hurtles inexorably toward Norsunder's final reckoning . . .
