So things are already pretty strange. But they're about to get much stranger.

When Cass's parents start hosting a TV show about the world's most haunted places, the family heads off to Edinburgh, Scotland. Here, graveyards, castles, and secret passageways teem with restless phantoms. And when Cass meets a girl who shares her gift, she realizes how much she still has to learn about the Veil -- and herself.

And she'll have to learn fast. The city of ghosts is more dangerous than she ever imagined.
