Listopia > Best S&F

Science Fiction and Fantasy (SFF) are my favorite genres in fiction.

This list contains best of science fiction books I have read – series and standalone.

Some of the books listed are absolute masterpieces in science fiction. And some like the many Military / Lost fleet series are pure entertainment. This is not an exhaustive list of everything I have read in science fiction, I have only included books I enjoyed reading ‘when I read them.’

Hope the list helps you pick up your next read. Enjoy!
