This is the third and final installment of The Viscount of Adrilankha, which began with The Paths of the Dead and The Lord of Castle Black. Brust has said, even belabored, that he meant this to be a single novel but the publisher said it was too long. It probably would be better to read all three volumes at once, and definitely a bad idea to just read this volume without having read the previous ones. If you've read Brust before, The Viscount of Adrilankha follows Five Hundred Years After, with many of the same characters and the same style of dialog and exposition.
This book itself picks up several threads of action which had been started in the previous volumes, starts a couple more, gets the action fast and furious in all of them at once, and manages to bring the characters' lives to some conclusions as it ties up the major world events. Definitely an enjoyable ride, but not as deeply satisfying as Brust at his very best. 8 out of 10.
