Catrina’s family is moving from sunny Southern California to Bahia de la Luna because it will be a better place for her little sister Maya to live.  Maya has Cystic Fibrosis, an incurable disease that affects the lungs and digestive system. Maya is obsessed with ghosts, and on their first day in Bahia de la Luna, the girls run into Carlos, who gives local ghost tours.  He tells the girls all about the ghosts in the community and later about the big Dia de Los Muertos celebration in November. Cat wants nothing to do with the ghosts or Carlos.  Cat gets a little freaked out when it comes to ghosts and anything scary.  It’s hard enough to move away from your best friends and get used to a new house, new town, and new school.  It’s hard enough to make new friends, but it is too much for Cat to have to deal with a town full of spirits and a little sister who seeks them out.
