Warrior Rising (Harlequin Nocturne Series #134)

Single dad Harrison Rand craved vengeance only for the harm the evil Esri race had inflicted on his young daughter. But now that he found himself the sole guardian of the Esrian princess Ilaria, exacting his revenge wasn't the simple task he'd thought it would be.

Because Ilaria—despite her cold beauty and royal entitlement—was like no Esri he'd encountered before. With a simple act of kindness, the princess made him question everything he thought he knew about her race. And to save his own from total annihilation, he needed her compassion and her power to seal the gates between their worlds forever. To save his soul, he found himself needing only her love.
