Sorry I did not get these posted last night. Exhaustion and a soft sofa lead to falling asleep much earlier then I expected.
First I would recommend all three of the Kane novels. The quality varies, but, imo, all three of them are worth the time to read.
Bloodstone, Dark Crusade, and, Darkness Weaves.
While the short stories do not contain as much Lovecraftian creatures, several are still good for their horror elements and creepyness.
The Dark Muse
I would recommend reading all the stories. IMO, Kane is the next great sword and sorcery character after Howard's creations.
the only problem being that the collections and novels are currently Out Of Print. And my understanding is that the Wagner estate is dragging their feet on allowing them to be reprinted.
So you may have to spend some time and money getting them.
+1 on this. I'm still new to REH & his characters, however, ever since I've heard of the Kane stories, from this forum in particular, I checked on Amazon & was lucky enough to get used copies of both Dark Crusade & Bloodstone, in great condition thankfully. I read Darkness Weaves (in pdf format), Dark Crusade & I'm currently reading Bloodstone. Kane is just as interesting and badass as Conan is (maybe even slightly more) and it's just awesome reading these stories considering how I've also became interested in the Cthulhu mythos as well.
Nevertheless, I definitely recommend all three Kane novels. Also, I heard that Centipede Press is reprinting the Kane novels and stories, does anyone know when these reprints will be released??
