3.5 stars 
 The audiobook is outstanding. Listening to the characters was incredibly fun. Had I read The Atlantis Gene instead, I probably would not have enjoyed it as much. I'm all for short chapters as much as the next person, but I don't want to be 20% going into chapter 25. WTH? This book is HIGHLY content-heavy. So many ideas. So much ambition. Nazis, time travel, Atlantis, plagues, aliens, genetic engineering, super spies, to name a few. Very well written. Not wordy, and to the point. And did I say this is a self-published novel? Bravo. While I think the story could have been way better (i.e. character development), I suggest giving it a read.
