A press release from HarperCollins UK:

HarperCollins UK announced today that it will publish for the first time in the UK the New York Times bestselling cult classic [[[Interworld]]] by Neil Gaiman and Michael Reaves, originally published by HarperCollins Children’s Books US in 2007. The novel will publish May 2013 alongside a global HarperCollins release for its newly-written sequel, The Silver Dream. The third book in the trilogy comes in 2014.

Interworld by Neil Gaiman and Michael Reaves will publish in May 2013 in paperback. The second book in the trilogy The Silver Dream (story by Gaiman, written by Michael and Mallory Reaves) will publish simultaneously in hardback. Ebooks will publish at the same time.

‘I am delighted to have this opportunity to work with the award-winning, bestselling, cult creator of books as brilliant and varied as The Graveyard Book, Coraline, American Gods and Stardust,’ said Ruth Alltimes, Fiction Publishing Director at HarperCollins UK. ‘It is so exciting to bring this to the UK market for Neil’s many dedicated super-fans, as well as to introduce a whole new set of readers to his imagination, sense of adventure and humour. These action-packed novels are the result of the collaborative genius of Gaiman, Michael Reaves and Mallory Reaves and we at HarperCollins are thrilled to be part of this collaboration too.’

Joey Harker isn’t a hero. In fact, he’s the kind of boy 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 his power to Walk. 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.
