Journeyed there and back again
If you like Bakker, Prince of Thorns might just be up your alley. Bother feature an anti-hero main character and a pretty dark storyline. Prince of Thorns has some interesting philosophical insights (through Jorg's internal monologue) into the nature of man, though not as deep as Bakker's work.
I may stick with Farseer for now and revisit POT after.
