to KostyaN Read Zelazny's "Night in October" or "Jack of Shadows," you'll definitely like them. In "October," the narration is from the dog Snuff's perspective, and it's so vivid that you feel like you're in the dog's skin, and October is so damp and cold. And "Jack" is a story about numerous betrayals and one friendship. And in general, it's rare when a negative character becomes the main hero.
Oh, yes. Also, "Lord of Light" - Zelazny himself considered this book his best work.
