Undercover Baby by Rebecca Winters

The baby surprise...

Diana Rawlins has turned up at the hospital with amnesia and a baby in her arms! She doesn’t remember how either of them happened. Her husband, Cal, is determined to get to the bottom of the mystery — especially since one of the things his wife doesn’t remember is being married to him!

Diana only seems to care about one thing — the baby Cal knows can’t possibly be hers. But he isn’t going to give Diana up without a fight. If the baby if the key to her heart, he’ll move heaven and earth to ensure that his new family can stay together.
