Stand-in parents

Rory expected Angel to look after his orphaned nephew. Under other circumstances, Angel would have liked nothing better -- she adored babies. But the baby was her ex-husband's love-child, and Rory was the brother-in-law who she knew had always been secretly attracted to her.

One look at the tiny baby and Angel was lost. She bonded instantly with him. She couldn't say no to becoming his stand-in mom -- even if it did mean having to move in with Rory. His baby -- he's sexy, he's successful ... and he's facing up to fatherhood!
