‘The kind of airship-dueling, guns-blazing fantasy that makes me wish I could pop through to the next reality over, join the Airish, and take to the skies’ Paolo Bacigalupi Everett Singh has escaped from his enemies with the Infundibulum: the key to all the parallel worlds. But his freedom has come at a price: the loss of his father to one of the billions of parallel universes in the Panopoly. E1 was the first Earth to create the Heisenberg Gate, the means to jump between worlds, but it was quarantined long ago. No one goes in . . . and nothing comes out. But E1 has something that Everett needs: the means to find his father. It’s lucky that he has the support of Airship Captain Anastasia Sixsmyth, her daughter Sen and the unique crew of the Everness, because Everett is about to discover the horrifying secret of E1 – and with it, his deadliest enemy!’Romantic, action-packed, wildly imaginative and full of heart’ Cory Doctorow
