I just finished reading WhatsHisFace. I think it might be Gordon Korman’s best work so far. A totally new twist on Romeo and Juliet parallels the life of Cooper Vega, aka WhatHisFace, the new kid in town. It’s a wonderful story that takes you out of wherever you are and into Cooper’s world, though not always his time period.
When 12-year-old Cooper Vega moves for the third time in five years, he receives a state-of-the-art smartphone to help him stay in touch with old friends. He's had phones before, but this one is buggy and unpredictable. When a boy named Roderick Northrop communicates with him through the phone, Cooper realizes that his phone isn't buggy at all; the thing is haunted!
