From Raina Telgemeier, the #1 New York Times bestselling, multiple Eisner Award-winning author of Smile, Drama, and Sisters!

Catrina and her family move to Bahía de la Luna, a small town on the Northern California coast, hoping that the cool, salty air will help her little sister, Maya, who suffers from cystic fibrosis.

Cat is not happy about leaving her friends, and becomes even more upset about the move when a neighbor informs the sisters that the town is inhabited by ghosts, and that Dia de los Muertos-- a time of year when ghosts reunite with their loved ones-- is coming up and is celebrated by the entire town.

Maya is thrilled about the idea of meeting ghosts, but Cat wants nothing to do with the Day of the Dead celebrations.

Can Catrina set aside her fears for the Maya's sake-- and for her own?
