"Personally I found volume 2 more satisfying, because I found the aliens, the "termites", more interesting than the humans. The Shshi are strange, as aliens should be, but relatable -- they plot against each other and have their customs and rituals and ways of doing things. Several of the Shshi are really fun characters, the scheming chamberlain, the child-like queen, the clever seer. Several of the warriors are especially complex as they are caught between duty and conscience trying to decide where their loyalties lie as the leadership of the termite city fractures."
Adam gave it 4 stars and recommended it. Most of the reviews of TQ have been 4 star (I've had one 5-star on each of the two volumes, and a couple of 3-star on v.1 -- nothing lower). I'm satisfied with 4 stars because this book does have so many elements to it (romance, a journey into human psychology, emphasis on future history, space travel, several types of extraterrestrials, conlangs, a low-tech alien culture with a tradition of heroic single combat, etc.), With a book so heterogeneous, I'm sure everybody will find something that annoys them, but (I trust) also something to like!
