Gravesong

Actor, singer... necromancer?
All the world's a stage... even when you're teleported to a new world. Struggling actress Cara O'Sullivan was walking down the street of Galway one moment, and the next, she was in an ancient tomb in a faraway world. Alone in the dark with her cell phone as her last tenuous connection to home, Cara sings her favorite song. To her astonishment, her song casts a spell of light into the world... and from the depths, something hears her. Challenged by a ghostly knight, a tragic necromancer, and hordes of undead, can a young woman who does not believe in heroes become one herself?
