To Desire a Devil (Legend of the Four Soldiers #4)

Nothing Is More Intoxicating
Reynaud St. Aubyn has spent the last seven years in hellish captivity. Now half mad with fever he bursts into his ancestral home and demands his due. Can this wild-looking man truly be the last earl's heir, thought murdered by Indians years ago? 
Or Dangerous
Beatrice Corning, the niece of the present earl, is a proper English miss. But she has a secret: No real man has ever excited her more than the handsome youth in the portrait in her uncle's home. Suddenly, that very man is here, in the flesh—and luring her into his bed. 
Than Surrendering to a Devil.
Only Beatrice can see past Reynaud's savagery to the noble man inside. For his part, Reynaud is drawn to this lovely lady, even as he is suspicious of her loyalty to her uncle. But can Beatrice's love tame a man who will stop at nothing to regain his title—even if it means sacrificing her innocence?
