The biggest thing to happen to Skary, Indiana, is renowned horror novelist Wolfe Boone-or, "Boo," as the locals fondly call him. For the past sixteen years, the reclusive writer has been the town's greatest attraction, having unintentionally turned the once-struggling Skary into a thriving tourist-trap for the dark side: from the Haunted Mansion restaurant, famous for its "bloody fingers" (fries splattered with ketchup) to Spooky's Bookstore (where employees dress like the walking dead).

But when a newly reformed Boone suddenly quits the genre and starts to pursue Skary's favorite girl-next-door, Ainsley Parker, the little town made famous by his writings becomes truly horrified. The residents know that the only solution is for Boo to fall out of love and get back to scaring.

Filled with humor, small town charm, and a gentle message of enduring faith, Boo shows how even the most colorful group of busybodies and hypocrites can become a community changed forever by God.
