I enjoyed this book. I was especially amused by the Commander posing as his own Ambassador, but I wonder how good the Commander's double was back in Ixia. I wish we could have learned more about the Magician's in the Magician's keep, and a bit more of how the day to day of that runs without all the side trips elsewhere. It was interesting in Poison Study to get to see some of how the palace ran day to day before they all went headlong into danger. I'm glad that all of the characters returned even though she travelled to another country, and I thought most of the new characters added to the story instead of just being filler.
