Cass (plus her ghost best friend, Jacob) is in Paris, where Cass’s parents are filming their 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 awakens a frighteningly strong spirit, she must rely on her still-developing skills as a ghost hunter - 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. 

Cass thinks she might have this ghost-hunting thing down. After all, she and her ghost best friend, Jacob, have survived two haunted cities while traveling for her parents' TV show. But nothing can prepare Cass for New Orleans, which wears all of its hauntings on its sleeve. In a city of ghost tours and tombs, raucous music and all kinds of magic, Cass could get lost in all the colorful, grisly local legends. And the city's biggest surprise is a foe Cass never expected to face: a servant of Death itself.
