The Silver Dream/Neil Gaiman and Michael Reaves/240 pgs./Neil Gaiman challenge

This is called the sequel to Gaiman and Reaves' The Silver Dream, but by the ending it's obvious there is at least one book coming. Also, according to the cover of the book, the story was conceived by Gaiman and Reaves, but was actually written by Michael and Mallory Reaves. Putting all of that aside, The Silver Dream picks up where Interworld leaves off. Joey Harker is a Walker--he can "walk" between dimensions. Originally from Earth (as we know it), Joey is now part of InterWorld, an "organization" whose goal is to keep the universe in balance. A new "person" enters the story line--Acacia Jones--whose true purpose isn't revealed until closer to the book's end. This is science fiction, action, and suspense all rolled into one. Middle -schoolers should find this very entertaining!
