The Spooky Chronicles: Greene Square Middle

Book 4 in the series.
It’s the start of a new school year (and a new school) for both “Spooky” Spencer and his buddy Donny as they begin the sixth grade. While Spooky’s suspicions of something supernatural pits him against a diabolical new adversary, trying to convince a crusading vice principal that he’s not a troublemaker may be his biggest challenge yet.

Meet Spooky, a dead little boy continuing to grow up. He goes to school, likes taking pictures in cemeteries, and doesn't breathe. Accidentally starting the zombie apocalypse is his biggest fear, but it’s not his biggest problem.

The Spooky Chronicles is a book series about a child who comes back to life as a zombie but is still getting older. Having already overcome personal tragedy in his life, his unique condition makes him aware of (and draws him into) a secret, paranormal underworld he never asked to be a part of (but still thinks is pretty cool).
