Devoting her life to the study of the ancient art of Lumeris-noire, Livia pursued her studies with the hope of becoming apprentice to the domain's defender. When she is finally granted the coveted position, she finds herself bound to a mysterious man of dangerous appetites. A man whose dark, tortured soul evokes an allure she can hardly resist.
Perrin, tainted by Fiendgen blood, spends his life isolated, deep underground, insulated from others by the very earth. For years he has remained alone, protecting Guthdry from utter devastation, but time is running out. He must train an apprentice to hold his position after he is gone. But no matter how he struggles to resist Livia, he cannot ignore the explosive passion that burns between them.
