Science fiction writers love sticking people in tiny metal cans and hurling them into environments where everything is trying to kill them, so it’s no surprise that some great SF books take place deep underwater, where exposure to the pressure kills people much faster than exposure to the vacuum of space.

On June 13, 2014, Reddit user sudevsen posed a question to the Books subreddit: What’s the best stand-alone science-fiction book of the last 25 years?
Reddit responded generously, including some titles that were older than 25 years (science fiction readers can be passionate, and if there’s a book you should read, by god they’re going to tell you, to hell with the rules).
sudevsen ended up with over 2,000 answers.

“Best” is a hugely subjective term, and not to be trusted. So here, “Best” means, “a consensus based on dozens of other lists, infused with my own personal bias.”
