Loved this book hard to put down can’t wait to read the next book. This was the best Sigma Force book I have read so far.

A great story. I love Rollins use of scientific facts to weave his story and it definitely does leave one thinking about our origins. I have my own personal belief about our Great Leap Forward in intelligence. Rollins never directly implies where the so-called teachers gained their knowledge. He didn’t mention the possibility of extra-terrestrial involvement. Just another theory drawn from the evidence. . .

Good book

Being a science teacher and a lover of adventure, I am always excited by another Sigma novel! This was a really fun read but not absolutely the best. I do love all the science at the backbone of these novels but this go round I found a few pieces seemed to be forced and unrelated. Don't get me wrong, it was still good but the two story arcs seemed to be a stretch in how they were connected. And I am not sure why Rollins has broken up the best buddy team in the spy world as it has been so long since Grey and Monk have teamed up. But I will for sure get my copy of the next Sigma book as soon as it is released.

This one kept me on the edge of my seat and crying at the compassion for the animals. Couldn't put it down.

The Bone Labyrinth was the first work of fiction that has me interested in reading the publications that support the storyline. Great read front to back.

This book was impossible to put down.

I usually just read free classics. I bought this book without even knowing who James Rollins is. The random gamble paid off. I don't think I've read a more complete book than this.

Having never read anything by James Rollins, nor this series, this book is a non stop page turner, with amazing insight, science, history and a true thought prevoking book! I plan on going back and starting from book one in this series, but it can be read alone without losing anything from the series.

Love, loved, loved this extremely interesting story by James Rollins! He has an affinity for mixing fact and fiction together to make the most complex, intriguing stories! One of his most compelling reads yet!!
