Kat didn’t believe in ghosts—until now. . . When Kat Sinclair’s dad tells her his new job hosting the ghost-hunting TV show Passport to Paranormal means they’ll be living on the road and visiting the world’s most haunted places, Kat packs her bags without a second thought. But the ghostbusting life isn’t as cool as Kat expected. The cast and crew don’t always get along, the producer’s annoying nephew has unexpectedly shown up, and Kat thinks the show—and her dad—might be cursed.

After a couple months at home dealing with her mother's upcoming wedding and trying on itchy bridesmaid dresses, Kat is more than happy to head off on another ghost-hunting adventure with her dad—especially since the cast and crew of Passport to Paranormal are headed to Brazil and Argentina, and her new friends Jamie and Haley will be joining them.
