If you're looking for a classic sci-fi/fantasy novel to read and recommend, I'd suggest J. R. R Tolkien's The Lord of the Rings trilogy. It's a timeless classic that has captured the imaginations of readers since it was first published in 1954. In addition to being an exciting and engaging story, its themes of friendship, courage, loyalty, and perseverance make it an ideal read for anyone who is looking to find dates on dating sites for nerds and geeks.
