A fabulous, and fast paced adventure set in multiple universes. Young Joey "walker" joins the interworld commandos as they struggle against the twin threats-- HEX and Binary. This story is filled with adventure, science and sometimes magic. It's fast paced and exciting. While many of the ideas seem whacky, the core ideas of the story are things that many serious scientists actually think about. Above all, this story is a fast , breezy read!

I read this book in about two days. A very interesting story, with enough humor and action to satisfy any reader. The only problem is the simplicity of the story, but all in all a great read!😀

As someone who is into the thought of parallel worlds, this book was a great read.

I agree with some of the other comments this story has far to much potential to just be a stand alone story I know that Neil Gaiman and Michel Reaves wrote this as a kind of preview for a tv show idea or something. But what you have received instead is a much better gift the power of a great new work invented by yourselves and it needs to be told.

Great

This book was excellent and don't let my following comments deter you from enjoying a fantastic story that plunges the reader into a mired of strange and fantastic worlds. The only qualm I have with the book is it's simplicity. Throughout the entire book I kept thinking, "wow, Neil is holding back." At first I thought it was intended to be a children's novel, like the Graveyard Book, which is totally acceptable, but some topics and phrases seemed to complex for children. It wasn't until I read the afterward that I learn that this was intended to be a teaser for a television series. It makes sense now, but it is unfortunate that something with so much potential, is dumbed down for television. I love Neil Gaiman and all his works, but this is not one of his best. It would be good for young teens or early high schoolers who will love the meshing of science and magic that the authors weave in Interworld.

I read the book in a day and a half - couldn't put it down. The storytelling is wonderful, rich with humor and intriguing ideas. The book mixes the best of sci-fi with the wonders of fantasy, making you wish it would continue without end. This is not a Neil Gaiman classic, but a combination of two amazing writers, that is more then the sum of it's parts. Enjoy.

Another great story from a great author. The mixture of fantasy and science fiction is beautifully done in the loving manner that few authors can match. My only regret for this story is that it is a stand alone novel instead of a series of books. Mr. Gaiman if you are paying attention I must say, please follow up this story. The worlds you have created here are far to vast to leave this at one story.
