Tunnel of Bones (City of Ghosts, Bk. 2)
Trouble is haunting Cassidy Blake . . . undead trouble.

Cass is in Paris, where her parents are filming their TV show about the world's most haunted cities. The TV show is fun, but little do they know about the true ghostly danger lurking beneath Paris, in the creepy underground Catacombs.

When Cass occidentally awakens a frighteningly strong spirit, she must rely on her still-growing skills as a ghosthunter - and turn to friends both old and new to help her unravel a mystery. But time is running out, and the spirit is only growing stronger.

And if Cass fails, the force she's unleashed could haunt the city forever.
