The Spooky Chronicles: The Terminal People

Still growing up as a dead boy, "Spooky" Spencer Lawson is learning about the strange world he never asked to be a part of (which is a lot more interesting than math). When a mysterious stranger he meets in an alley appears to die after touching Spooky's hand, Spooky begins to wonder how dangerous he really is, especially to the people he cares about.

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).
