I have really enjoyed the Sun, Moon, Sand, and Star novellas and can't wait to start the full-length novel Upon the Sands! I was a little underwhelmed by the first book in the series, but they have got better and better. If you feel like you don't really care for book 1 but enjoy Jeremy's writing style, I'd strongly encourage you to give at least book 2 a go, as that is (from my point of view) where things start getting interesting!
I wish Jeremy's books were more widely-known, as he has created an exciting massive world where I, at least, love to get lost :)
A real surprise
This book is the best in the series so far. Strangely, I was about to DNF it about halfway because I was confused as to what was going on, but I persisted (or rather, I paid a little more attention) and ended up loving it. The way in which the same story is told from three different points of view is masterfully executed. I can't wait to start the next instalment!
