This is the book that turns many of the things that we've learned in the previous books into their ear. Corwin is, of course, in the middle of everything racing thither and yon mostly in the Shadows. We learn some things about Dara, Brand, and the other characters. But are the people telling these things really trustworthy? We are also told some things about what the various plotting factions are doing but can we trust this info either? We just don't know. If we can trust it, some things are becoming clearer.
However, I can't really trust any of them and I'm occasionally struck by Corwin's desire to trust his siblings even though he thinks all the time that he can't trust them. I was also a bit disappointed that so little came from their ancient rivalries. Centuries of hating or at least disliking each other is thrown away with a hand shake and: "I guess you've changed"? If I had been born and raised to expect the worst from my siblings I probably wouldn't have been able to shake it off so quickly.
Of course, Zelazny isn't writing a fat fantasy and I'm actually happy to be spared of hundreds of pages of angsty introspection of "should I trust him or not". Just seemed a bit quick, that's all.
On the other hand, I'm not entirely happy with the way he keeps changing the rules. In the first book Corwin thinks that he can't takes his troops with him through the Trump. However, in the next book the solders are moved with the use of two Trumps and by this time it's an established fact of moving. Horses can go through, too. Now, of course, in the first book Corwin might just not have the time to move the soldiers. However... I didn't get that impression. So, Zelazny thought it would be cooler (not to mention easier for the plot) to change it. The problem is that the reader can never know what "rule" is going to be changed next. And now with the Pattern, well, shouldn't one of the intrepid explorer siblings have found out the truth before now?
But it's also a clear sign of the strength of Zelazny's writing that (at least this) the reader starts to think of these things instead of just dismissing it as "just fiction, of course it doesn't make sense". Amber is a fascinating setting.
The publisher and I are making final revisions to the Zelazny text and noticed again something a bit odd:
"a straw-tick mattress in the corner." near the start of the eight chapter on page 100 in the Great Book when Corwin is in jail.
Is this just a typo and should be straw-thick or does it refer to a tick infested strawmattress?
