He unknowingly walked through a star gate or portal to another world. The planet Cornu was settled by humans in the distance past who came through gates from Earth.

The Alt Apocalypse is the ground-breaking, genre-bending series from Tom Abrahams. It explores survival under the most extreme circumstances, but with a twist (and no cliff-hangers). This series, which can be listened to in any order, features the same core characters in each complete story. But every book dunks them into a new, alternate apocalypse; a nuclear holocaust, an earthquake, a flood, a wildfire, a hurricane, a plague, and even zombies.

Cynical Jacob Hornblower has followed his brother, Caleb, back in time, hoping to convince him to return home. His mission is soon forgotten, however, when he finds himself captivated by Liberty's spitfire sister, Sunny. But can a man who is down on love truly understand the unbounded strength of the human heart?

“At one point they tried to calculate when time began, when exactly the earth had been created,” begins Time Shelter’s enigmatic narrator, who goes unnamed. “In the mid-seventeenth century, the Irish bishop Ussher calculated not only the exact year, but also a starting date: October 22, 4,004 years before Christ.” But for our narrator, time as he knows it begins when he meets Gaustine, a “vagrant in time” who has distanced his life from contemporary reality by reading old news, wearing tattered old clothes, and haunting the lost avenues of the twentieth century.

For a policeman, there can be few things worse than a serial killer loose in your city. Except, perhaps, a serial killer who targets coppers, and a city on the brink of bloody revolution. For Commander Sam Vimes, it all feels horribly familiar. Caught on the roof of a very magical building during a storm, he's found himself back in his own rough, tough past without even the clothes he was standing up in when the lightning struck. Living in the past is hard, especially when your time travel companion is a serial killer who knows where you live.

When Rigg and his friends crossed the Wall between the only world they knew and a world they could not imagine, he hoped he was leading them to safety. But the dangers in this new wallfold are more difficult to see.

But they will have little choice.

Molly Moon returns...and bumps into earlier versions of herself, four of them, to be exact, all kidnapped and transported back in time to nineteenth-century India by Molly's most fearsome nemesis yet, an insane maharaja.

The only thing standing in his way is Molly and her brave pug, Petula.

Cassandra Penelope Dankworth is a creature of habit. She likes what she likes (museums, jumpsuits, her boyfriend, Will) and strongly dislikes what she doesn't (mess, change, her boss drinking out of her mug). Her life runs in a pleasing, predictable order…until now. Then, something truly unexpected happens: Cassie discovers she can go back and change the past. One small rewind at a time, Cassie attempts to fix the life she accidentally obliterated, but soon she'll discover she's trying to fix all the wrong things.

When you discover the world is a computer program, and you figure out that by altering the code you can time travel and perform acts that seem like magic, what can possibly go wrong? Pretty much everything. Just ask Brit, who has jumped around in time with such abandon that she has to coexist with multiple versions of herself. Now, Brit the Elder finds that her memories don't match Brit the Younger's.

Now that Pern can look forward to a future without the threat of Threadfall, the people are free to leave their protective stone holds and spread across more of the planet, as well as improve their lives with the newly discovered ancient technology. Not everyone is happy, though. Some resist the change, and consider anything new to be an "abomination".
