17. Size 12 is Not Fat

This was a cute, fun, chick-lit mystery. I'm behind the times and the sequel is apparently already available so that will be another one on the list shortly I'm sure. :)

Here's a review from B&N:

Bag the tiara and get out the gun: Heather Wells, former teen idol, turns detective in the cute debut of a new mystery series from bestseller Cabot (The Princess Project and other titles in her Princess Diaries series). After the 20-something Heather's rocker boyfriend dumps her, and her mother and manager flee with her earnings, she becomes an assistant director of an undergraduate residence hall at Manhattan's New York College (read: NYU) in hopes of free tuition. When students start to die mysteriously while "elevator surfing" in the building, weight-conscious, romance-obsessed Heather goes on a crazed hunt to uncover the truth-with an unwavering sense of style. As Magda, Heather's dorm cashier friend, says: "Even if the rest of your life is going down the toilet... at least your toes can still look pretty." Cabot delivers Heather's amateur sleuthing adventures in a rapid-fire narrative that may leave some readers begging for time-outs to control sudden laughing fits.
