The Gates (The Samuel Johnson Series)

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...

Can one small boy defeat evil? Can he harness the power of science, faith, and love to save the world as we know it?
