Kat didn't believe in ghosts--until she became a teenage ghostbuster. . . 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 and ghostbusting 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. But the ghosts in South America are just as spooky and unpredictable as the ghosts they encountered in Europe, and once again Kat finds herself involved in some mysteries that she might not be able to unravel.
