Tunnel of bones - Victoria Schwab

The thrilling sequel to Victoria Schwab's New York Times
bestselling City of Ghosts!

Trouble is haunting Cassidy Blake . . . even more than usual.

She (plus her ghost best friend, Jacob, of course) are in Paris,
where Cass's parents are filming their TV show about the world's
most haunted cities. Sure, it's fun eating croissants and seeing
the Eiffel Tower, but there's true ghostly danger lurking beneath
Paris, in the creepy underground Catacombs.

When Cass accidentally 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.
