Chains of Frost (The Bellum Sisters Series #1) (paranormal romance)

When a will from her dead father decrees outrageous succubus Chloe into the protection of the renowned vampire commander, Tyrian en Kulev, she does what any desirous creature would do and casts a spell. But, when the spell she casts summons an ancient demon from deep within the earth to kill her and her sisters, she knows one place can keep her safe. Tyrian's castle of death set in the frigid icy snows of Northern Europe. Chloe thought she'd despise Tyrian, but instead she feels a rapidly blossoming tender for him. From the scar running along his cheek, to the bitter chill in his gaze, something about Tyrian makes Chloe want to keep him close until she could learn his true colors. 

Tyrian en Kulev always pays his debts. When Francis Bellum dies and orders Tyrian to act as his eldest daughter's protector, Tyrian resigns himself to what should be an elementary task. All he had to do was keep her alive, then, debt paid, as far as he was concerned. But the beautiful succubus comes to him with a deadly demon trying to kill her and an alluringly upbeat attitude that invades his thoughts and soon his heart, whether he likes it or not.
