When Newbery Medal winner Neil Gaiman and Emmy Award winner Michael Reaves teamed up, they created the bestselling YA novel InterWorld.InterWorld tells the story of Joey Harker, a very average kid who discovers that his world is only one of a trillion alternate earths. Some of these earths are ruled by magic. Some are ruled by science. All are at war.Joey teams up with alternate versions of himself from an array of these worlds. Together, the army of Joeys must battle evil magicians Lord Dogknife and Lady Indigo to keep the balance of power between all the earths stable. Teensand tweens and adultswho obsessively read the His Dark Materials and Harry Potter series will be riveted by InterWorld and its sequel, The Silver Dream.

An astounding tale of adventure, danger, magic, science, friendship, spaceships, and, oh yeah, the battle to save all the people in all the worlds in all possible dimensions.

Joey Harker isn't a hero.

In fact, he's the kind of guy who gets lost in his own house.

But one day, Joey gets really lost. He walks straight out of his world and into another dimension.

Joey's walk between worlds makes him prey to armies of magic and science, both determined to harness Joey's power to travel between the dimensions. The only thing standing in their way is Joey?or, more precisely, an army of Joeys, all from different dimensions and all determined to save the worlds.

Now Joey must make a choice: return to the life he knows or join the battle to the end.
