Alias Mummy by Linda O. Johnston

Rugged doctor Reeve Snyder had saved her and delivered her baby girl. He was her hero — the kind of man she would have liked to have as a friend...a lover...a father for her baby. If only...

Polly Black had been running from something — someone — when the accident had landed her in Reeve's care. He didn't want her gratitude; he wanted the truth, and he wanted her — for the three of them to be a family. Somehow he had to convince Polly that the only place worth running to...was straight into his arms.
