Young Samuel Johnson and his dachshund, Boswell, are trying to show initiative by trick-or-treating a full three days before Halloween, which is how they come to witness strange goings-on at 666 Crowley Road. The Abernathys don’t mean any harm by their flirtation with the underworld, but when they unknowingly call forth Satan himself, they create a gap in the universe, a gap through which a pair of enormous gates is visible. The gates to Hell. And there are some pretty terrifying beings just itching to get out. . . .Bursting with imagination and impossible to put down, New York Times bestselling author John Connolly’s "wholly original" (People) and "refreshing" (San Francisco Chronicle) novel is about the pull between good and evil, physics and fantasy. It is about a quirky and eccentric boy, who is impossible not to love, and the unlikely cast of characters who give him the strength to stand up to a demonic power.
