I do have several favorite books from various genres, to pick one is simply impossible. One book that left a lasting impression on me and has been one of my favorites for several years is “Wintergirls” by Laurie Halse Anderson.
This is by far one of the best books I’ve read in the YA-genre and by far the best book I have read which is dealing with eating disorders.
I wrote review of the book back in 2011, and Laurie, herself, complimented my review on twitter. You can read the review here: Wintergirls.
