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.
