The Anomaly by Michael Rutger

If Indiana Jones lived in the X-Files era, he might bear at least a passing resemblance to Nolan Moore -- a rogue archaeologist hosting a documentary series derisively dismissed by the "real" experts, but beloved of conspiracy theorists.

Nolan sets out to retrace the steps of an explorer from 1909 who claimed to have discovered a mysterious cavern high up in the ancient rock of the Grand Canyon. And, for once, he may have actually found what he seeks. Then the trip takes a nasty turn, and the cave begins turning against them in mysterious ways.

Nolan's story becomes one of survival against seemingly impossible odds. The only way out is to answer a series of intriguing questions: What is this strange cave? How has it remained hidden for so long? And what secret does it conceal that made its last visitors attempt to seal it forever?

My take:  I found this book to be really interesting.  I thought the beginning of this book was a bit heavy on setting up the rest of the book which was almost half the book.  But when we get to the secret cave things start to happen and we don't know what is going to happen but we have that feeling at the back of our neck and the hairs raise up telling us that something creepy is going to happen.  This book was very good and I was pleased with the outcome and would recommend it to anyone who likes thrillers.  Just don't give up in the first part of the book and get bogged down in the details, the last half is well worth the wait.  

I received a review copy of this book from Grand Central but the views are my own.
