I remember reading these when they first came out and being really frustrated because there was a huge gap between the publication of the last two books. Sadly, I don't remember a lot about the books themselves though reading the names rings a bell. Beyond that I know I was pleased with the final resolution and was able to walk away from the universe in a good frame of mind.

Have you read Tailchaser's song? That was the book that got me into Tad Williams. The reference to Watership Down caught my eye and I really enjoyed it though not to extent I did W.D.
