Conversations with the fat girl by Liza Palmer and I have to say, since
Jennifer Crusie's Bet Me I haven't enjoyed a book this much even if the book is written in first person narrator AND present tense (something I really don't like and my prof at university thought it is the downfall of all literary greatness 'lol'). It takes skill to write in present tense, and clearly this author has the skill.

We meet Maggie, a chubby young woman of almost 28 years who has a BA in Arts and MA in art restauration but works in a coffeeshop and lives with her dysfunctional dog Solo.
Over the years she had several crushes and one or two dysfunctional relationships. Everyone around her seems to get on with their lives, except for Maggie. Even her best friend formerly fat Olivia who is now an illusive size 2 has met her dream man and is about to marry ... and Maggie is to be the maid of honour. But as Maggie changes her life and takes the plunge to actually work in her studied profession, after she is forced to move homes on a 48 hours eviction, the fat girl in the duo realizes that best thick friends at 12 might not survive a thin relationship at 28.
