A very cool end to the series! I liked how after the human and the regular construct experience we now got the ooloi construct view of the world. To me, many things we were shown in the earlier two books grew clearer, even if this books story in itself wasn't groundbreaking. 3.5-4
Interesting to learn more about the Ooloi experience.
