In Ghost Crypt, the Drews are hired to investigate paranormal activity in the Tube in London. Strange things are afoot while the train is in motion, including doors opening unexpectedly. Also, passengers have reported frightening apparitions.

When Ellen and Monty go underground, they discover that some construction may have stirred up ancient ghosts. After the possession of a Tube passenger, Ellen knows the spirits are searching for something - or someone. But what? Or whom?

Ellen's need to communicate with the spirits in ancient languages means she has to play medium with the help of a translator. When the investigation lands them in the center of an ancient conflict, they encounter a mysterious force that may keep the spirits from going into the light.

As Ellen balks at continuing on the case, Monty realizes they must choose between freeing the Tube from its hauntings and risking their own lives.

Will Monty and Ellen break the case before someone gets hurt on the Tube? Or before they do?

Ghost Crypt is a ghost-packed paranormal investigation with spirited thrills, spine-tingling paranormal interaction, and humorous moments. This is Chanel Smith's second novel.
