A Goodreads user asked:
So, it's the first in a series. Will I be unhappy with the ending or should I just wait for all the books in the series to come out? I passionately hate cliff-hanger endings.
Douglas Beagley I would wait. In many ways, the entire first book is a "preparation". It explains things and builds up. It does not resolve.
Erik Herndon I would read the book. The way everything ties together is remarkable! I just finished the second book, the Obelisk Gate, and feel like I may need to reread and I believe the third is due this year.
Ken Wilson The ending was not a complete resolution but was a good stopping place and one of the most imaginative endings I have ever read. Really beautiful ending but wait till the end to read it.
