People are disappearing in Montreal. Jack and Mojo believe they are being drawn into the "Other City", an ephemeral city that appears at random, and suddenly vanishes, taking people with it. There's a blind street musician whose haunting accordion echoes down the narrow streets of a city that may only exist somewhere "next door to reality".

While Jack Flanders is being chased by a zombie, his phone rings. It's Mojo waking Jack from his nightmare and inviting him to New Orleans. Later, strolling through the French Quarter, Jack is amazed to see Claudine, from Montreal. Or had he just met a voodoo priestess who can shapeshift into the woman of his dreams? And who is that zombie that keeps following him?

Somewhere in the tropics, yet another beach resort is being built. As they bulldoze a road through a valley the locals consider sacred (the dwelling of a Nature Spirit), the jungle begins to spring up everywhere else. At Maria's Cafe', chairs are sprouting leaves, vines are creeping over the counter, and orchids are growing from the walls. Meanwhile, Jack, Mojo and Claudine are attempting to prove the Nature Spirit not only exists, she may have just begun to "even the score".

People feel there's something "witchy" about Amy. She is tormented by an oval "light" that appears at random. Amy fled to Costa Rica, where she was born, but the light has reappeared. Jack and Mojo try to help, but something very powerful is happening, and it may be traced back to an old African god.

Jesse, a young anthropologist, disappears somewhere in the highlands of West Sumatra, and Jack is hired to find her. There's evidence that she was involved in the Kabut cult, a secret society practicing ancient tribal magic. Jack travels to Bukittinggi as the city erupts in the exotic sounds of celebration at the end of Ramadan, the Moslem holy month of fasting. Sounds just dandy - until a mist swirls around him, and he's staring into the gaping mouth of a giant, swirling vortex.
