About 4 chapters in I thought Dan Brown. 10 chapter in I thought Inferno. It stirs eventually away from this ( maybe not narrative wise) though. 
 I have to be honest here. When I read the preview I was very excited about the book, but now that I got through the first part of the trilogy I am underwhelmed. 
 The first 80% (from my kindle tracker) was a confusing blur or changing narrators and locations- jumping around the globe as if with a finger on a map. It took me about the first part to get a firm grasp of the plot, too long in my humble opinion. There was a constant 'why are you talking about this? What is the point of these people?' Questioning, which shouldn't last that long for people to enjoy the story or the characters. (view spoiler)[Having said that, killing josh was a nice touch, kind of build a character, make people like it and then let it go- which was a twist I thoroughly enjoyed, The Pierce's diary narrative was also a nice touch. (hide spoiler)] 
 Back to the topic, the book tries to tackle way too much without really expanding or paying too much attention to the details. To name a few: archeology, evolution, eugenics, genetics, the missing link, Atlantis, aliens or higher beings, xenophobia, conspiracy theories, bioweapons and epidemics, secret organisations, 9/11, reversed time travel?, spatial teleportation...way too much with the given narrative. 
 BUT it was enjoyable for some of so let's see how the sequels fare.
