A solid follow-up to the series that answers many questions
“In this follow-up to Book 1, Donoghue similarly provides an Indiana Jones–like mélange of archaeology, treasure, villains, jungles, and ancient science. (Although it’s possible to follow this book as a stand-alone volume, it’ll make more sense read in sequence.) His characters are well-defined, important in a story so driven by the particulars of how an unknown technology works, sections that will be best appreciated by readers with a taste for engineering.”
