A daring doctor sets out to cross unexplored Africa aboard a balloon of his own design, taking two companions along for the ride. What begins as a bold scientific wager turns into a flight over jungles, deserts and rivers no European has ever mapped.

A stubborn professor deciphers an old runic note and drags his reluctant nephew down the crater of an Icelandic volcano toward the heart of the planet. Guided by a calm local hunter, the three descend into a world of underground seas and ancient stone.

With the war over, a club of American artillery enthusiasts grows restless and hatches a wild plan: to cast a giant cannon and fire a manned projectile at the Moon. Half satire, half engineering dream, the novel follows the whole daring scheme from first idea to launch.

A message in a bottle, half eaten by seawater, hints that a lost sea captain is still alive somewhere along a single line of latitude. A yacht and its crew, joined by the captain's children and a scatterbrained geographer, set off around the globe to work out where exactly he might be.

Sent to hunt a mysterious sea monster, a French professor and two companions find themselves aboard something far stranger: a fantastic submarine commanded by the brilliant, brooding Captain Nemo. From that moment the ocean itself becomes their prison and their wonder.

An impeccably punctual English gentleman bets his fortune that he can circle the globe in exactly eighty days, and sets off that very evening with his new French valet. Trains, steamers, elephants and a dogged detective on his heels turn the wager into a breathless race against the clock.

Fleeing a siege by balloon, a handful of castaways are dropped by a storm onto an unknown island in the middle of the Pacific. With almost nothing in their pockets but knowledge and grit, they set about building a whole small civilisation from scratch.

When disaster strikes the crew of a whaling ship, a fifteen-year-old apprentice is suddenly the only one left who can command her. Barely more than a boy, he must bring a handful of passengers safely across the ocean, unaware that a hidden danger is quietly steering them off course.
