His Rebel Heart (Harlequin Super Romance Book 1993)

Can a rebel ever change his ways? 

Being a single mother and successful florist is tough, especially when your new next-door neighbor is the man who shattered your heart. Eight years ago, bad boy James Bracken walked away from Adrian Carlton…and their unborn child. Now he's back. And Adrian's desire to protect her son from the truth of his biological father isn't enough to hide the wild blue eyes of father and son, or to keep Adrian from surrendering to the raw passion between her and James. But is he truly the changed man he claims to be? Maybe this time his rebel heart really is home to stay.
