Robert E. Howard. Conan the Conqueror. Sphere, 1974 (originally published 1936). 191 pages.
An outline of the plot would read like a laundry list of the worst fantasy/adventure cliches, but it’s fun anyway. The writing is a mix of efficient storytelling and extremely corny language, which is perfect for the story. But most importantly, Conan is the baddest badass of an antihero you could hope for.
