After nearly drowning (or maybe actually drowning), Cass has a new best friend (Jacob, who is a ghost) and she has the ability to pull aside the Veil and step into the world of the dead. Although she knows it's dangerous, she just can't stop going between worlds. She doesn't tell her parents, who are experts in the supernatural, and when they take her to Edinburgh, Scotland, she is overwhelmed with ghosts who make even greater demands on her. Cass must figure out what her purpose is and how her best friend Jacob is involved. It's a vivid introduction to Edinburgh and some of its gruesome history. This creepy story is a solid choice for 6th and 7th graders. It's the first in a series, with the next two books taking place in Paris and New Orleans.
