Search - Perfect Double (Treasured Tales II) (Loveswept, No 660)

The back cover says:

"Logan--a master of seduction whose disguise meant a chance for love... Saved by a stranger from a near fatal mugging, business mogul Logan Prince woke up in a strange bed--and found a reluctant angel with a siren's body bandaging his wounds! Touched by her compassion and lost in Carmen Sanchez's dark eyes and soft caress, Logan made a daring bargain with his look-alike rescuer, trading places with the cowboy drifter so that he might taste the lady's fire and learn her secrets.

An impossible dream who'd staked a claim on her heart... Desperate to be cherished by a man who'd put her happiness first, Carmen melted in Logan's arms adn surrendered her soul. But when he confessed his charade, she felt only anger at his betrayal...and the fear that she'd never fit into the world where he belonged. Could a man who had everything but someone to live for win the trust of a woman who gave him the only gift that mattered?"
