Welcome, Caller, This is Chloe, by Shelley Coriell

When junior Chloe is dropped by her two "best friends", and her advisor turns down her proposal to do her individual study on Villanous Vixens- The Not-So-Squeaky-Clean Women of Daytime Soap Operas, she finds herself finding refuge (and a project) trying to help turn around the school's student-run radio station.
This was a fun read, with some solid characters and a refreshing protagonist in Chloe.
I did like it that Chloe had good relationships with her family, and I found the issues her grandmother faced were handled with great sensitivity..
