Ten-year-old Gabby isn't scared to spend her summer break traveling with her father for his ghost-hunting podcast. After all, she doesn't believe in ghosts. She's more into science and history. It's up to her to debunk the hauntings her dad investigates in the most haunted places in America. With each new adventure, Gabby uses her skills to figure things out . . . and finds out that sometimes, not everything can be explained.
