The Billionaire Next Door by Jessica Bird
A nice little contemporary romance... my only concerns were
- Lizzie was too much of a Mary Sue character and
- After a guy accuses you of being a gold digger TWICE you still want to be with him? I think not, unless of course, you are a gold digger, which I don't think she was, but in the back of her mind, she gotta think, "dude, he's a billionaire, I'll deal with some crap."
