Ian's struggle to hide his secrets had me turning the pages quickly, scared things would fall apart and he wouldn't get a happy ending. Things did fall apart - real life isn't all rainbows and sunshine and the author did not shy from making things hard for Ian. I found the fact that Ian relapsed into his eating disorder believable. Disorders can be a life long struggle and it's important for those suffering to know it's not weak of them to relapse and have to climb back on the wagon. The fact Ian is a boy suffering from bulimia is important too seeing how you see a lot of stories about girls struggling with it, but not many boys.
Overall, MB Mulhall wrote a brilliant and important story dealing with eating disorders. The teenagers were believable, and the romance between Ian and Julian was sweet (bordering cheesy a few times.)
