Everything, Everything discussion

Okay, so I don't have mush I can say about it but I read this book last year that isn't even that popular so this a long shot but it was about this 3 year old girl who had just lost her mom (to cancer I think) and then it goes through that next school year. It had sections for every season and some random things I remember was like, she would call her mom's cell phone and once the voicmail went of she would talk to her and she had to join a support group at her school for kids who had lost their parents. I also think they visited some place in Asia at one point. I know that' not much to go of here but if you know it please tell me because google is not being much help this time. :( (Ignore the book at top that was by accident)
