I liked this book, but for some reason I didn't enjoy it as much as the first Poison Study. However, this didn't stop me from devouring the pages! I think what diminished my enjoyment of this story was that it got too bogged down with different plot elements, I think too much was added. Although nothing was left unresolved everything seemed rushed and there was very little detail in her explanations. For example, when Yelena and her brother reconcile, there was only a page spent on this despite the fact that it had been a theme throughout the book.
But despite feeling a little rushed, I did like it, it introduced some new characters such as Kiki, Yelena's horse and Cahil Ixia who is supposedly the dead King of Ixia's nephew and is desparate to win back his crown and wrestle Ixia away from Commander Ambrose.
I am greatly looking forward to the next and final book in the trilogy to see how everything is resolved.
