Ever since Cass almost drowned (okay, she did drown, but she doesn''t like to think about it), she can pull back the Veil that separates the living from the dead . . . and enter the world of spirits. Her best friend is even a ghost. 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. NYT bestselling author Victoria Schwab delivers a thrillingly spooky and action-packed tale of hauntings, history, mystery, and the bond between friends (even if that friend is a ghost . . .).
