I am continually amazed by Grace Draven's skill at world building, and her ability to create characters that are so easy to stand behind and root for. I have yet to read a book written by Draven that I was not completely invested in. 
 I loved Radiance, and I knew walking into Eidolon that I probably wouldn't love it quite as much, and while I was right, I still thoroughly enjoyed this read. It has been said in many other reviews - but you 
 should not read Eidolon without reading Radiance. 
 The beginning of this book had me very close to tears. I could not tell you the last time I have been so emotionally invested in new characters so quickly and truly. Draven holds no punches and really really sets up a strong foundation for the emotional tone of Eidolon. 
 I enjoyed every side character as much, if not more, as I did previously, and still found myself rooting for Ildiko and Brishen - although I could have done with a little less angst and bitter fighting against their situation. I understand the importance for the plot, but I just could have been solid with less of the she loves me, she loves me not. (view spoiler)[I am, however, very impressed that Draven did not just stick a miracle-pregnancy on Ildiko, because I feel that has been done (and done poorly) so so many times and I personally have had enough. In addition, what I loved most the little Queen was her presence throughout the story rather than her popping up at the very end which made it less forced and less "miracle" baby. I loved that she was "nothing" important to her family and was therefore blessed in her escape. I also really enjoyed her entourage and found myself wishing for MORE of the three of them and their everything. Backstories. Future. Whatever. (hide spoiler)] 
 I gave this book a three rather than a four simply because it couldn't fully live up to Radiance (but I didn't expect it to) and for the back and forth angst which really could have been toned down the tiniest bit. I look forward to Draven's future work, especially the next installment of the Wraith Kings.
