The Temporary Roomie by Sarah Adams

Drew Marshall may have let me move into his spare bedroom while my house is being renovated, but don’t think for one second his kindness comes without strings. Big, ugly, fake relationship strings.

That’s okay, though, Dr. Andrew. I’ll agree to your terms, move into your house, and act like your girlfriend when the big day comes; but I also plan to make your life miserable—make you pay for what you did to me.
