Poison Study by Maria V. Snyder

I fell in love with this book, this character and this author. Unfortunately, I never finished my review when I read it. Yelena is such a strong, fearless and relentless heroine. If you love fantasy and young adult stories, you cannot miss this series. It is one of my all time favorites and I went on to devour anything else Maria Snyder wrote. I highly recommend this series.
