quick easy read with likable characters

From back cover:
From the moment the gorgeous, sexy stranger washed up on shore, millionaire Jarrett Wilkenson was suspicious. Since he was one of the most eligible bachelors around, women were forever using strange antics to propose. And while this captivating visitor's amnesia routinewas unique, he wasn't going to let her beauty distract him...
Though Jarrett didn't have much choice but to let the woman with no memory stay in his home until someone claimed her, he was going to keep his fortune and young niece far away from her. Yet as Harrett observed her natural maternal instincts at work, he couldn't help wondering about his mysterious guest's past...and future...with him.
