I'm assuming if you want to read a Conan book you're not looking for political correctness or a non violent solution to lifes problems. Good. This is sexist caveman fantasy at its best, set in a world where every female is scantily clad and voloptuous, be they an assassin, a princess or a serving girl, every tavern is dangerous, full of violent men, sexy women and bartenders willing to part with gossip for a coin or two (or a punch in the face from Conan) and every city has en evil sorceror intent on harnessing the power of an old God in order to take over the world (insert evil laugh here).
The best thing about this world is how atmospheric and descriptive it is. The constant references to opulance and wealth, silks and gems, traders and nobles leave you wanting to wrap yoourself in silk and lay down on gold cushions for the afternoon, while the poverty of the street children and the beggars who grovel in the dirt of the poor districts leave you feeling dirty and cheap. The book gives just the right amount of detail without ever becoming boring. Dont worry, there is never long to wait before the next fight. Conan gets into fights a LOT.
Speaking of wealth, this is where Conan our Cimmerian barbarian thief truly shines, not in having his own wealth, but acquiring that of others. Most of his adventures start with a 'simple theft' that goes horribly wrong, usually forcing the poor soul to sleep with gorgeous women after rescuing them (sometimes before too) from all sorts of evil villains and monsters.
This is fantasy escapism at its best. Light, easy to read, fun and exciting, highly recommended.
