Luna - Kelvinian Warriors, #2

Earth as you know it is gone. The humans who survived the Toxic War now possess the power of the elements; earth, water, wind, and fire. The sectors must work together to survive, but inter-elemental matings are forbidden.  Luna is a Thornican princess, an earth elemental huntress, and future queen to her people. Her duty is to protect the fertile lands from all enemies, even the male who invades her dreams. As an ice warrior of the Kelvinian people, Prince Kole has a bounty on his head.
He'll kill in service to the crown, unless the assassin is his future mate. With the elemental nations locked in battle, will his female sever his head or claim his heart?
