From New York Times bestselling author and legendary storyteller Alan Moore, the second novel in the Long London Series, a daringly inventive fantasy novel about murder, mayhem, and magic.

It's 1958 and Dennis Knuckleyard has decided to leave his adventures in the Great When in the past where they belong. For nine years, he's avoided so much as thinking about the magical version of London, until he rediscovers an unpleasant reminder of his last adventure—a key that he'd secretly brought into his own world from the other for safekeeping.

But while Dennis may believe he's done with the Great When, it's far from done with him. When Dennis gives the key to a friend, its magical properties reawaken, bringing creatures from the other world into Dennis's and sparking riots in Notting Hill. Even worse, Dennis's old crush Grace Shilling has been forced into the Great When to investigate strange happenings in both cities.

Desperate to keep Grace safe, Dennis follows her into Long London. But once inside the other city, it will not let him go away again so easily, and Dennis and Grace must fight to set things right in the Great When and their own world, or forever lose their lives—and each other.

Full of Moore's characteristically stunning world building and rollicking prose, I Hear a New World is the extraordinary second adventure in the Long London series.
