The Lost World

A peaceful day of exploration turns deadly when a sudden explosion traps Marguerite and Roxton in an underground chamber. Their only hope for escape is Challenger, but the same explosion has left him with no memory of who he is, or what has happened to his friends. Meanwhile, a contest of friendly rivalry between Veronica and Finn leads to an enigmatic discovery at the Treehouse, as another memory from Veronica's childhood is literally uncovered. Faced with certain death, Roxton and Marguerite reveal emotions best left buried, so that even if they do survive their ordeal, there's a chance their relationship will not.

When Challenger discovers the wreckage of a World War I transport plane, he's captured by its pilot, Lieutenant Drummond. Drummond has been stranded for five years since the crash, protecting the plane's cargo—a crate of iridium ingots stolen from the Royal Navy. Challenger is astounded to see the iridium because it had been intended for his secret wartime research. The sight of it prompts him to remember the night five years earlier, when he was questioned about the theft by two British intelligence agents working for MI5. Back on the Plateau, when Challenger and Drummond arrive at the Treehouse, Marguerite recognizes the iridium, too—she also was a suspect in its theft, and she recalls her own MI5 interrogation, the same night Challenger was questioned. Amazing twists and turns. We find out that there may be more than just coincidence that has brought our small group to the plateau.

Challenger, Roxton, and Marguerite take Finn to a cave where one year earlier a blinding light opened a doorway to another reality. Once inside, the explorers witness an eerie apparition of a man Finn recognizes and fears. But when Finn races from the cave, the three figures who follow are not her friends-they're Kayle, Una, and Rixxel, three demons who have taken the place of Challenger, Roxton, and Marguerite. If the demons can remain on the Plateau for two days, they will permanently replace the explorers, and Kayle will be free to bring chaos and destruction to the world. In the final deadly showdown between Finn and the demons, Finn must make the decision of her life-save the future or save her friends. Until an unexpected sacrifice changes everything…

Using the Plateau's mysterious energy lines as a source of power, Challenger constructs a machine to send the explorers back to London. But when he, Roxton, and Marguerite find themselves in the same place they started from, they conclude the machine is a failure and head back to the Treehouse-only to discover the Treehouse is gone! While investigating what else has changed, Roxton is captured by slavers with automatic weapons and stripped-down cars, and learns the shocking truth-he and his friends are in the year 2033, eighteen years after an apocalyptic war devastated every place on Earth except for the Plateau.

Alone in the jungle, Veronica hears piano music and follows it to its source - a 19th century German village that has suddenly appeared in a fog choked valley. To her surprise, the handsome musician, Thomas Ducart, announces that he wrote the beautiful melody for her. Flattered by the musician's attention, Veronica takes him to the Treehouse, but Challenger is concerned. He fears that Ducart's village may be unstable, and Veronica could disappear into another dimension if she returns to the village with Ducart. Even more disturbing, are Challenger's ill feelings about Ducart's designs on Veronica, but Challenger's warnings only drive the beguiled Veronica further into Ducart's passionate embrace.

When a blindingly bright meteor strikes the Plateau, Challenger, Roxton, and Marguerite set out to investigate the impact site. But the closer they get, the colder the temperature becomes. As the explorers turn back, they discover what appears to be a victim of the intense cold - a beautiful, blue-skinned woman, unconscious and nearly frozen. To save her life, the explorers take her back with them. When the frigid temperatures reach the Treehouse and all attempts to warm the woman makes her condition worse, Challenger suspects that things are not as they appear. Roxton and Marguerite are attacked by a group of blue-skinned male warriors and the truth becomes clear - the heat-absorbing meteorite now buried in the Plateau is the first step in a terrifying invasion of creatures who need the cold to survive.

When a powerful witch named Dame Alice feels threatened by Challenger's science, she calls upon her two beautiful acolytes to help undo his power. In order to earn full witchhood, the two must lure Challenger's ""guards"" - Roxton and Malone - to the witch's castle while she goes head to head with the ""wizard"" - Challenger - herself. While the two young witches distract Roxton and Malone, Dame Alice visits the Treehouse for a visit. In spite of Marguerite's protests and warnings, Challenger is intrigued by the witch's power and too easily lowers his guard. When Dame Alice sabotages Challenger's newest invention and almost kills him, it is only Marguerite's quick thinking that saves the scientist from his own folly. But in the end it is not Challenger's life that is in danger, but the lives of Roxton and Malone….

When Roxton happens upon a hangman's noose dangling from a lonely tree in the jungle, he's suddenly transported back to the American West where he finds himself at the end of the rope. Facing him is Challenger, but in this world he's known as Sheriff Jack Challenger, a cruel lawman who neither recognizes Roxton nor listens to his plea of innocence. Saved by a rancher's widow, Roxton begins a strange journey to clear his name and find his way back to the Lost World. Along the way he runs into all of his friends but none of them recognize him -- Malone is a cold-hearted gunslinger, Veronica runs the local saloon and trading post, and Marguerite is the beautiful widow who saved Roxton's life. As Roxton struggles to make sense of it all, he is drawn to a final showdown in the saloon, where he must face his friends in a deadly shootout.

When Malone finds a knife, he is transported back to the East End of London in 1888, the scene of Jack the Ripper's brutal murders. In the nightmare of his visions, Malone sees his friends playing key roles in the crimes, both as conspirators and victims. Meanwhile, Veronica is approached by a famous British doctor, who enlists her to help find his missing knife. Could this man be Jack the Ripper? Or is it the Scotland Yard Inspector who runs into Roxton and Marguerite? Charmed by the Inspector and his claim to know a way off the plateau, Marguerite is eager to assist him in apprehending the Ripper. Marguerite realizes she could be walking into a deadly trap. Veronica is left to confront and defeat the infamous killer to prevent the murderous cycle from being repeated on the plateau.

While exploring a mysterious dinosaur bone yard, Roxton is attacked by a charging Ttriceratops and kills it, not out of necessity but in anger. However, the bone yard is actually a sacred animal burial ground, protected by a beautiful, half-human, half-dinosaur guardian named Oseena. To punish Roxton for his crime, Oseena curses him to become the prey in a hunt that will end only with his death. Shaken by his encounter with Oseena, Roxton returns to the treehouse, but the hunter tracks him relentlessly and then captures Marguerite, using her as bait to lure Roxton into a deadly trap. Roxton returns to Oseena's burial ground to confront the hunter and save Marguerite.

There's no escape for the Challenger Expedition when Captain Askwith's mysterious airship explodes in a fiery crash. But moments later, when Challenger, Roxton, and Marguerite appear on a British air station in 1915 -- on the same day the airship was launched on its final mission -- they realize they truly have taken the place of the captain's original crew. After two years of struggling to escape the Plateau, Challenger and his friends must now fight to return to it by once again taking flight on the doomed dirigible. At the same time, Veronica appears on the Plateau, and in a shocking confrontation with Captain Askwith, realizes she has her own mission to complete: pursue Askwith and somehow return him to his ship.
