Reddit reviews Warlord of Mars Omnibus Volume 1

I can recommend this edition of Dark Horse Conan. They feature original REH's stories adapted to graphic novel form. It is now available in an Omnibus collection, however I would stop at Omnibus 2 as the writers and artists were replaced with untalented hacks later in the run.

Born on the Battlefield is also a good read. It's a Dark Horse original story about Conan's youth. Also the Dark Horse King Conan books are good. They are adaptions of REH stories as well.


I can speak for this edition of John Carter, it was very good and highly recommended.
