Book excerpt: When Liam O’Reilly insisted on being a part of Laura’s world again, her first instinct was to turn him down. It wasn’t that she didn’t find him attractive. But in the time they’d been apart, Laura had married, had a baby and been widowed. She was older and wiser now. What really bothered her was that if Liam had stayed all those years ago, he would have discovered the secret Laura now felt compelled to keep — their son.
