An epic tale across hundreds of pages. Ghost-seeing Luna is the only one who can talk to the ghost of her little brother who died in childbirth. Curiously, even as a ghost Matthew continues to grow and begins to accompany Luna to school having as close to a normal childhood as he can. While the other ghosts Luna encounters all seem to dissapear to the afterlife eventually, Matthew looks like he'll be sticking around. Good thing too, since evil and dark magic seem to be afoot. Can Luna, Matthew, and friends save the world?

From the publisher: “Twelve-year-old Luna can see the ghost of Matthew, her little brother who died in childbirth. Along with their youngest brother, Additya, the siblings navigate the triumphs and trials of middle school: birthday party invitations, Civilizaciones Antiguas class, and summoning the courage to talk to Luna's crush, Frida. But now, they must embark on their most challenging quest yet: to find and confront Flaith—a nobleman-turned-monster from the Second Golden Age-and Death himself. Along with their friends, the gang encounters magical weapons, the infamous Trio, the most haunted house in America, and an ongoing battle to fight off Flaith and save each other.”
