When Michael O'Brien and his father, James, buy a new car just in time for the family's summer vacation, James signs over more than the title to his old AMC Gremlin in his rush to buy the brand new Inferno station wagon. Joining them on the trip are Michael's creepy younger siblings, Elvis and Olivia; his overbearing mother, Mary, and her pet Chihuahua, Lucky; his backwoods aunt, Margie; and the cremated remains of his grandmother, June, whose dying wish was to have her ashes scattered in the Grand Canyon. Can the O'Briens pull together to defeat the possessed station wagon, or will the forces of evil destroy the family in the process? Find out in this humorous coming-of-age story.

"Gronlund transports us so well into the great tradition of the American road trip that I'll offer a warning: if you, like me, have memories of being wedged between siblings and panting dogs for hours on end, you may find yourself in tears by the end, both from nostalgia and the relief that you're now too big to be crammed into that backseat ever again."- Mark Hosack, author of Identity; screenwriter of Give 'Em Hell Malone

"Barring androids and certain born-as-adults aliens, I think everyone can find something to love in this hilarious, well-drawn coming-of-age story."- Shawn Kupfer, author of the 47 Echo series
