Guess Who's The Daddy? Thanks to her anonymous sperm donor, a baby is about to be more than a gleam in Dr. Paige Brennan's eye. So why the Safe Harbor obstetrician just agreed to further complicate her life with a roommate, she'll never know. She still can't decide whether ex-detective Mike Aaron is irresistible...or just plain irritating. Though it is nice to have a man around the house. Until Paige gets the sneaking suspicion that her baby's "anonymous" father is none other than her new roomie. Helping out couples with fertility issues is one thing. Raising his own child is something Mike never envisioned. But the mother-to-be is bringing out his protective instincts. And some other feelings he didn't even know he had. Things are suddenly moving a little too fast. Or is Mike right where he belongs? On the fast track to fatherhood?
