A weird and wonderful conclusion to Severian’s story. I really loved this book, though maybe had my expectations set lower because of the way I hear people talk about it but I was really pleasantly surprised.

The super trippy, timely whimey, PKDian fifth book to the books of the new sun. It's sort of a novel length epilogue to the tetralogy. I didn't think it was as good, but even so Gene Wolf's writing is beautiful, and it does answer many questions that were left unanswered at the end of the Citadel of the Autarch.

Despite some interesting ideas, the expansion of the lore of The Book of the New Sun's universe leaves too much productive ambiguity lost. The act of resolving and explaining so many outstanding questions from the original tetralogy, not to mention hammering home the religious/historical allegory that Wolfe brings into focus in Citadel, saps the joy and curiosity from the wonderfully abrupt ending of the original series.

I did enjoy some of the conceptual ideas in Urth, but it's hard to recommend when the tetralogy is so wonderfully mysterious right up to its conclusion. I don't like reading The Book of the New Sun as a series of puzzles to be solved, and Urth seems to pointedly invite such readings.
