I loved the humor and suspence!

The book started out a little slow, but by the middle it picked up speed with many mysteries beginning to unfold and unexpected twists.

The book was weird at the beginning but got better as it went on and ended great.

This book was good, it was about the Mars rovers, Spirit and Opportunity, what they did and discovered throughout the years.

This was fantastic from start to finish.

This is a very good book that is action packed. It was one of my favorite Clive Cussler books. It was about an expotition that turned into a secret mission to stop the Japanese from taking over the world with there robotics. I loved reading it it was so we'll written.

Fast, easy reading but the typical 4-stories-in-1 book. Feels like the author realized their page quota was almost fulfilled and the story needed to end so it was abruptly completed. Not the best book I've read but certainly not the worst.

This was recommended to me rather enthusiastically by some of my students back in January, and while I read it slowly alongside a few other books, the weight of it settled on me as I considered how big global events change everything, even (or perhaps especially?) the day-to-day operation of schools. The global event in this novel is World War II, but the flashback-style narrative is about how a young man comes to understand the circumstances of major events of his youth. It was terrific, and I book I'll remember reading for sure.

It is a very exciting book with many unexpected challenges and amazing discoveries.

It's a step up from the disastrous CROSSROADS OF TWILIGHT, but still not containing enough story for a 900-page novel. The general loss of focus on what matters--the reawakening of apocalyptic, time-unraveling evil and the cost of what it will take to defeat it--has really harmed the long-term impact of the series, as the last two books have had nearly none at all.
