"If you're a fan of the show, or just someone who likes to be confused, delighted, and horrified (in that order!), then you're in luck!" -- Dust jacket.

When Blendin Blandin needs help searching for the Time Pirates' treasure he goes to Dipper and Mabel, embarking on a journey through time from the drgon-infested medieval era and the wild west to the giant-baby-and-laser filled future.

For their summer vacation, twelve-year-old twins Dipper and Mabel Pines travel to the fictitious town of Gravity Falls, Oregon to spend the summer with their Great Uncle Stan Pines (often shortened to Grunkle Stan), who runs a tourist trap called the "Mystery Shack". Things are not what they seem in this small town, and with the help of a mysterious journal that Dipper finds in the forest, they begin unraveling the local mysteries.
