Hah, you're the first person i've ever found that has read them other than... well, my mom who introduced me to them. I've read the first 5 (the Corwin ones) too many times to count, and the Merlin ones once.
Tis an awesome series! I've read it all the way through I think 4 times now, & turned my oldest son onto the books as well..yay for moms passing on the good book mojo!
And swords (the knight, queen and king of swords) was written by moorcock... Skelator (the band i'm in) are huge moorcock fans and have a few songs about Corum and such.
Ahh that explains it, I think of the Corum books as the Corum books & the Saberhagen series as the Swords books..damn authors writing about similar stuff *g*.
Who's your favorite incarnation of the Eternal Champion? I think Corum's mine, though I do have a fondness for Elric too.
