meh.. Thats all I can really say for this book. I literally skimmed through it all. I felt like I should at least try and attempt to read it considering it was the last and final book in this trilogy. I really did love the first book, it had everything a great book needed! Amazing protagonist, gruesome history, romance, climax and even great supporting characters. Maria V. Snyder really made you feel for her characters in Poison Study. Now that I think of it, after reading all three books, Snyder kind of lost the characters original.... (took me a while to find the right word haha) personas or even their original nature that they started with in the first book. This only correlates with Valek, Yelena, Irys, Ambrose etc. The only two characters that didn't really change were Janco and Ari, which I was happy about :) Thats pretty much all I have to say about this series! 
 Thank you Snyder for the perfect first book, Poison Study.
