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!".

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.

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?

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.

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.

In the small Caribbean town of San Miguel, Jack and Mojo begin to hear stories of islands that appear and disappear. They soon discover there are strange ghost-like beings that visit the town when the islands appear. They are called, Luc-an-oona (those who bless us). But when one of Jack's crew visits the ghost island, strange things begin to happen.

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".

From Rio de Janeiro, into the vast Amazon, Jack pursues a mysterious crystal skull. The author and composer recorded the music and sounds of Rio, and then flew into the dark heart of the Amazon to record the jungle sounds. Also featuring Mojo Sam.

Jack is led by a crystal skull to the ruins of a lost city in the Amazon. One night, an ethereal city appears hovering above the ruins. Jack climbs to the top of a pyramid temple, and is drawn up into the city.

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".
