I enjoyed this story. This the debut book for this author and the writing felt new at times. There were places in the book that lacked depth and a bit of repetition in reminding the reader about the heroine, Yelena's, deep dark past. The story moves along nicely and I enjoyed the characters. Yelena is a strong female lead and shows nice transformation by the end of the book. I was a bit disappointed by the quick ending, however. I thought the pacing up until that point was quite good, then we zipped right along and in 50 pages a whole mountain of action was accomplished. I would have liked it to be written out a bit more. If possible, I would give this book a 3.5 instead of a 3.
