Size Doesn't Matter by Meg Cabot

Heather should be happy. She’s finally got a boyfriend and although he was only supposed to be her "rebound guy", things have gotten serious fast . . .

She's also actually passing her first college course, and better yet her dad’s moving out.

On the down side, her boss, Dr. Veatch, may well be the most boring man on the face of the planet . . . But that hardly seems reason enough to put a bullet through his head.

Can Heather find her boss’s murderer, answer Tad’s question, and get her landlord Cooper to realize that by letting her go, he’s making the biggest mistake of his life, all while maintaining a fifteen hundred calorie per day diet?
