The Wrath by Gena Showalter

Bestselling author Gena Showalter returns with a new book in the tantalizing Rise of the Warlords series, featuring a brutal Hell king and the irresistible beauty who upends his world.

For centuries, Rathbone the Only, King of Agonies, has existed for one purpose: recovering the enchanted bones of his slain wife to bring her back to life. He’s never been closer to success. But a new enemy has risen. A band of deadly war gods who have thirty days to destroy her or suffer the consequences. With time running out, Rathbone hires a maddening harpy-oracle, unaware she has an agenda of her own.
Neeka the Unwanted is a fierce warrior on a mission: stop Rathbone and the gods. She’s seen the future if either is victorious, and it’s horrifying. She’ll do whatever proves necessary to forge a new path, even seduce the ruthless royal from his purpose. What she can’t predict? How the intense male will shatter her hard-won defenses along the way.
As Rathbone battles unexpected betrayals, cunning foes and the wild temptress he craves with every fiber of his being, he knows he must choose: hold on to a cold dream or embrace a new flame.
