Page-turning fantasy novel set in post revolutionary Mexico, drawing on Mayan folklore and mythology, as set down in the Popol Vuh. Not sure if it is considered YA, but it's appropriate for young readers. Makes many Mexican history references, without incorporating them too deeply into the story. Some elements reminded me of Stephen King (evil hotel, quests, Maine=Yucatan, Middleworld). There were also some rom-com elements. The ending was very silly.
