I recently finished "The Last Invisible Boy" by Evan Kuhlman.
Finn Garrett, 12 years old, is writing a journal after the sudden death of his dad. Finn is trying to make his way through a really hard time in his life while his mom, brother Derek, and grandfather are doing the same. Part of Finn's journey is complicated by the fact that his hair is turning white and he is getting progressively paler. He is fairly sure he is becoming invisible. As he navigates through his year without his dad, he speaks to you the reader in a clear, believable voice. He is at times funny, sad, scared, happy, lost and determined.
Here is a quote from Susan Patron who won the Newbery medal two years ago that I think you will find interesting.
