Affliction

"A relentless disease. No cure. And no way to stop it.
The Alt Apocalypse is the newest ground-breaking series from Tom Abrahams.
It explores survival under the most extreme circumstances, but with a twist (and no cliffhangers). This series, which can be heard 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.
Different heroes will emerge in each novel. Different characters will survive and perish. Your favorite character dies in one book? He or she will be back in the next. In the end you'll unwind the loose thread that connects every character and every stand-alone story.
In Affliction, Abrahams tells the story of a mysterious team of researchers, four college friends, an ex-con, a lonely fry cook, and a secretive group of prepared civilians as they each battle to survive in southern California after an outbreak of a new, deadly disease with no known cure.
Can they find a way to stop it? Can they survive in an afflicted world?"
