Size 12 Is Not Fat by Meg Cabot
Heather Wells was a teen pop star, burning up the charts, and touring the malls. But at the age of 18, she has already started to fade out. Between losing her record contract and her mother making of with her fortune, Heather is left to make some life changing decisions. She wants to get an education. So, she takes a job at New York College as an Assistant Director in a residence hall. Which does not pay well, but after a 6 month probation, Heather can attend classes for free.
When not one, but two, freshmen girls are found dead in the elevator shaft, the police are quick to rule the deaths an accident, but Heather, following her own hunches, plays PI investigating the truth.
Really fun chick lit/cozy mystery. I liked the main character a lot and look forward to reading the next two books in the series.
