Ah, how this thriller captured my heart. I cried a little bit at the end, it was so beautiful and sad in some moments. The story is interesting, thrilling, adventurous and heart capturing. As always, Mr. Rollins chooses two sides in this book, one historical and one scientific and presents them extremely interesting: experiments with animals, the ties between the guerilla and man and of course, a stunning view to the human brain. 
 The book has all my beloved sigma heroes (due to sad hint in the end I think that something sorrowful happened to Kowalski, I hope he's ok, PLEASE don't kill him!) and new ones - the wonderful twins with the cool priest, not forgetting Baako and the relationship, that unfolded. I just loved that little guy and how the author used sign language to reveal this stunning story. 
 Also the real condition of the Zoo in China (described in the book and mentioned in the notes at the end) was chocking. I'm glad that James Rollins revealed this situation in his book, so maybe the China government could change things to better, even a little bit. 
 The author does a really good job to show how Baako looks at the world, the little guy is very trusting, has sharp sense and a very emotional understanding of life. The best episodes are among Baako, Maria and Kowalski. 
 Rollins skilfully blends extreme action with gripping plot, combining interesting historical and scientific facts. A stunning book that is heart capturing and action packed.
