While Jack Flanders is scuba diving in the great barrier reef off Belize, he discovers a sunken pirate ship. On board are two skeletons poised as though playing chess, and every time he returns, the pieces have been moved. One of the pieces looks a lot like Jack.

Jack and his crew accept an invitation from an eccentric billionaire who has built a castle on a Carribbean island. What first appears to be a replica of a medieval fortress turns out to be a very high tech castle, with robot valets, and rooms with floor-to-ceiling plasma screens. In the middle of the night, Jack's crew begins to encounter their own "personal demons", first in their dreams and then right before their eyes.

Mojo receives a call from "The Whistle Stop Hobby Shop". He's told his pocket watch has arrived. It's a gift from someone named "Rufus". But the pocket watch has no hands or numbers, just an opaque face that reminds Mojo of a zombie's eye. Mojo is mistaken for the detective, Rufus. He's hired to find Angelina, the missing sister of Philadelphia gangster Tony Rizzo. By using his watch as a portal, Mojo is able to look beyond the veils of this world, and he traces Angelina to a mysterious train.

Jack Flanders and his crew sail to a mysterious island known as Key Diablo. When a fog moves in, all color seems to vanish, and everything turns into black and white. The islanders, dressed in clothes from the 1940s and '50s, appear to have stepped out of an old Hollywood film noir. And soon our heroes, Jack, Claudine, Mojo, Dominique, and Rose, find themselves playing characters that are dressed to kill.

In a little theatre, off off off Broadway, Simon Gray is attempting to direct a production of Macbeth, but every actress who plays Witch #3 disappears. Simon calls in his old friend, Mojo Sam. When Mojo sees an actress vanish before his eyes, he brings in Little Frieda. When Little Frieda plays Witch #3, she also disappears. When she reappears in the Realm of the Muse, Little Frieda meets the real Witch #3, the one Shakespeare based his character on, and she is sizzling mad and out for revenge.

Jack Flanders encounters trolls, wizards, and all sorts of odd mythical creatures when he explores the "Invisible Realms" in search of our future Ah-Ha's - those spontaneous flashes of insight that have caused great thinkers to leap to their feet and shout, "Ah-Ha!".

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".

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.

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".

Invisible balls of energy are causing hallucinations within the walled city of Old Quebec. Jack and Mojo try to locate the source of these "eyes". When a little girl with pigtails, smoking a cigar, is seen about town, Jack suspects Litte Frieda is involved. When Jack speaks to Claudine on his cell, she appears before him; when he hangs up, she vanishes.
