White Knight — C.D. Reiss

From NY Times Bestseller, CD Reiss...Catherine's long-lost love is found.

Catherine Barrington is a rich girl. Chris Cartwright is a poor boy.
He left her to make something of himself. A man she could be proud of. A man she could bring home to her parents. A man she could marry.
On the trading floor he became the man he knew he could be. Now, it's time to return.
Rich girl.
Poor boy.
She didn't care about his money, but he didn't believe her. Soon after he left, all the money was gone. 
Her life is hell.
Now he's back, and he's different. Pristine. Gorgeous. Rich. 
Rich boy.
Poor girl.
Money was never the barrier, until now.
