Marty's Science Fiction Recommendations

This is a list of science fiction books that I quite liked and would recommend to other people who might like science fiction.

I seem to particularly gravitate to "hard" sci-fi, space opera, utopian fiction, and (like all objects with mass) black holes.

Story title links are to full text. List is not complete or comprehensive.

Also see the Ithaca Generator Sci-Fi club monthly book list, notably to compare which of those made my list.
