Her Secret Guardian

Description for HER SECRET GUARDIAN by Sally Tyler Hayes:

PROTECTOR IN THE SHADOWS

He'd been dubbed her guardian angel, this man who came by night to warn Dr. Grace Evans and her medical team of coming danger. Grace had never seen his face, but his velvet voice reached out of the darkness, stirring longings she blushed to name. Though a tragedy had made Grace wary of love, she dreamed of her personal hero. Then she was kidnapped...

Soldier Sean Douglass had private reasons for keeping a distant watch over Grace. But to save her now, he would have to get closer than ever before. In intimate quarters, their explosive passion would not be denied. How long could he keep his identity - and feelings - a secret?
