I am being generous with the 2 star rating. This trilogy should never have come to fruition, Poison Study should have been the only book. Magic Study was a disappointment and now Fire Study was a terrible bore. The writing style has seemed altered since Magic Study and Fire Study suffers from it even more. The "world" and all the elements of it established in Poison Study feel lost and nonexistent now. I found Yelena growing increasingly annoying and foreign to the Yelena from Poison Study. Valek has been patchy in both Magic Study and Fire Study and when he does show up, he is a shell of his former self. If I had to read him calling Yelena "love" one more time I was going to throw the book.
Overall a disappointment.
