Science fiction and fantasy offer a rich legacy of great books â from Asimov to Pynchon, there are some fantastic, ambitious works of genre fiction out there. But they’re also daunting. So a lot of us just muddle through and pretend to have read these classics â which isn’t that hard, because they’re everywhere, and we’ve heard people talk about them so many times. We SF fans are good at pretending. But these books are classics for a reason â and they’re worth reading.
