She'd run out on him

When Sarah Colby was seventeen, she made the biggest mistake of her life. Her marriage to Reece Colby was in trouble, they were nearly destitute and their baby was sick. When Sarah's mother-in-law offered a solution, Sarah listened. Elizabeth Colby would look after Reece and baby Drew--if Sarah left. Seeing no other alternative, Sarah walked out.

But now she's back

Twelve years later, Sarah's still trying to live with herself. Then she learns that Drew's in trouble and she knows it's time to return. But how can she face Reece after deserting him? And what will happen when he finds out about Lyssa, the daughter he doesn't know he has?
