Did you like The Atlantis Gene? I've almost pulled the trigger at Amazon a couple times but the reviews seem hit or miss and my reading list is already so long.
I enjoyed it. I also finished the other two books in the series which ties it all together. I can see where the reviews would be very binary though. It brings up some possibly controversial scenarios which requires some suspension of disbelief. It's almost Fantasy more than Science Fiction in that regard.
I tried the first book but could not choke it down. It's crap, and I say that as someone who usually doesn't mind iffy writing if the story is entertaining.
