content: This was my first Clive Cussler book. I didn't realize that I was jumping into the 15th or 16th book in the series. I can't wait to go back and read the previous ones. This book combines ancient history and adventure, as well as politics and the military, in an effort to provide a first-rate novel. The character development that went into this book and the series is phenomenal and is second only to the creative storyline that keeps you guessing until the end. If you like me are a fan of paperback novels packed with action and adventure this series is for you.
