'Chock-full of awesome,' says Paolo Bacigalupi, 'the kind of airship-dueling, guns-blazing fantasythat makes me wish I could pop through to the next reality over!'

There is not just one you, there are many yous. We're part of a multiplicity of universes in parallel dimensions - and Everett Singh's dad has found a way in.

But he's been kidnapped, and now it is as though Everett's dad never existed. Yet there is one clue for his son to follow, a mysterious app called the Infundibulum: a map not just to the Ten Known Worlds, but to the entire multiverse - and someone wants to get her hands on it . . . very badly.

If Everett's going to keep it safe and rescue his dad, he's going to need friends: like Captain Anastasia Sixmith, her adopted daughter and the crew of the airship Everness.

'Romantic, action-packed, wildly imaginative and full of heart' Cory Doctorow
