The Crimson Castle — Samantha Holt

With her father dead and her brother missing in the crusades, Lady Evelyn finds herself in the clutches of the notorious Lord Tibald. But while she should be concentrating on spurning the advances of the lord, Evelyn fights a growing attraction to the enigmatic and brooding Gabriel, Tibald's darkly unnerving right-hand man. As she becomes aware of Gabriel's merciless nature, she struggles to reconcile herself with the consuming nature of their bond, while trying to understand the two sides of the conflicting man. All the while, Lord Tibald plots to get his hands on Evelyn's lands...and her.
