On the frozen plains of Kassouk, where a few aliens rule a medieval Human world, Tora, Human warrior trained by tigers, seeks her father’s murderer. But what she finds at the point of her sword confuses her. How dare Dragomir, the handsome Mutant, question her bloodline and her loyalties? And could a new enemy control the savage hordes of the fringe? Dragomir offers to help, but Humans and Mutants are forbidden to fraternize under penalty of death... Should Tora trust her mind, her instincts, or her heart? In the vortex of war, treason and intrigue, among blizzards, avalanches and ambushes, Tora sets out to solve the mystery of her father’s death. When she unveils the secret of her birth, she realizes Dragomir is the key, and together, they must save their planet from the invaders and fulfill their destiny... if they can survive dire persecutions from those they mean to protect.
