==Book Description==
Second chances in love are hard to come by... — Since his wife, Nancie, divorced him, Wren Nickelson has felt like a failure. But finding himself with spare time, Wren decided to take up the one thing he's always wanted to do: write. — One day as Nancie drops off their two daughters for a weekend visit, she spies Wren's manuscript. Unable to squelch her curiosity, she begins to read it -- and after finding that her ex-husband has used her name for the selfish heroine, Nancie feels she must finish the story.
Before long, she's confronted her husband's caring and sensitive nature, characteristics she'd always known he had, but which she'd taken for granted. She also comes to understand his faith -- a factor that led to their divorce.
Realizing the error of her ways, Nancie decides she wants her husband back.
But is she too late? Have Wren's dreams caused him to fall in love with someone else?
