Someone To Watch Over Me by Lisa Kleypas

She couldn't remember who she was...A temptingly beautiful woman awakens in a stranger's bed, rescued from the icy waters of the Thames, her memory gone. Told that she is Vivien Rose Duvall, one of London's most scandalous beauties, she finds herself under the protection of enigmatic, charming Grant Morgan. Her life is in his hands. Deep in her heart, she knows he has mistaken her for someone else...
He was the only man she could trust. As one of London's most eligible, and unattainable catches, Grant Morgan is a man who has known every kind of woman. And the one in his arms now seems so innocent, so vulnerable, that he can't help but be enchanted. And as his love for this mysterious beauty grows, he's determined to unravel the secrets of her past and discover the truth no matter what.

This is the first book in the Bow Street Runner series. Grant Morgan doesn't care for Miss Vivien. Seems when he snubbed her, she told everyone she turned him down. When Grant finds Vivien almost drowned, he decides to take advantage of her. He wants to hurt her like she hurt him.

This book was good. It wasn't great, but it had a good story line. I didn't like how Morgan wanted to hurt Vivien in her vulnerable state. Loved how he had to apologize to her in the end though. All in all a good read. I give a C.
