Pandora

"Over 100 players enter a virtual world to play a game – survive 24 hours of their chosen apocalypse. Instead of game over at the end, they're plunged straight into another game, and then another. They have no communication with the outside operators. Their simulation pods are designed to only last 3 days. The artificial intelligence is tapping into their minds and creating 'death dreams'. And they're trapped in a dangerous world with strangers they can't trust. It's clear something is keeping them inside the game, but who or what? Everyone dreams of escaping reality but this game has far greater risks than they could have imagined..." ― quoted from this book's product page on the Amazon.com website as of 2019-01-01.
