The Last Monument

Great story, well-developed characters, an enjoyable read! Looking forward to the next book in the series.

Interesting read, but Nazis again? The story theme is kind of a rip off of Indiana Jones: Raiders of the Lost Ark.

Excellent Adventure Starter. For those who like their adventures to be Indiana Jones type - including both going into the jungle and facing down Nazis - well, have I got a book for you. This combines that basic style with Grumley's usual science/ science fiction bent to produce much more nuanced characters who have much bigger personal stakes than his “breakthrough” series, to great effect in the closing moments. About the only negative is that the final confrontation... isn't really there. At least not what could have been the really cool parts. Still, while I'm not as intrigued about this new series as I was in BREAKTHROUGH by the end of its first book, I definitely want to see where Grumley goes with this. Very much recommended.

One of the most original and twisty plots I have ever read! Outstanding thriller with history and sci-fi! Well-written with no shortage of creativity!

An Engaging Adventure in the South American Jungle

An enjoyable and fairly quick read with a good blend of adventure and raw human emotions within a context of history and mystery as well.
