The Chronicles of Amber are my first exposure to Roger Zelazny, and he continues to impress me with what I imagine is a very difficult combination of concise, uncluttered dialogue paired with expansive and world-building concepts and plot twists. 
Zelazny's precise and varied use of his comprehensive vocabulary had me looking up words more frequently than I usually do - which I enjoy! Good examples of this are words like "recrudescence" and "etiology," neither of which I think I have ever heard a human speak in a conversation but turned out to be perfectly suited to their context. This kind of baroque-sounding dialogue is actually perfect for the main characters of this book as they all seem to be like a royal court of related and competing influence peddlers.
The political/familial intrigue (they end up being pretty much interchangeable) continues to ramp up with a murder, a pair of stabbings, a trip into a cloud city that's much creepier than Bespin, and a literal phantom limb. The book ends

on a cliffhanger that truly confused me, as I believe Zelazny intended.

The only reason I'm not proceeding directly to Chronicles of Amber #4 is that I'm reading these in a giant 10-book compendium and my wrists need a couple days off from holding it up. So far, that 10-book monster compilation is shaping up to be some of the best value for a book in recent memory. Here's hoping it continues.
