5/5/2017 update: Just finished the audiobook, and it was fantastic. Highly recommended audio experience. 
 Original review (6/2/2016): 
 Sleeping Giants is so weird... and I loved it. 
 The entire story is told through transcripts, a series of interviews and journal entries that, once pieced together, tell the story of a world-changing discovery and the lengths one man in particular will go to see the project through to completion. 
 While there are a handful of recurring central characters -- Kara, the gutsy helicopter pilot, Vincent, a linguist, Dr. Franklin, the project leader -- the main character is really the unnamed person conducting the interviews. He (I'm pretty sure it's a he) sets the wheels in motion for the entire project, and has a cold, logical approach that seems brutal at first, although over time we can also see his brilliance and his absolute mastery of manipulation, even on a global scale. 
 The hand initially discovered is only one piece of an artifact that will, over the ensuing years, be pursued and retrieved all across the world -- even if that involves entering foreign air space and initiating near-catastrophic political and military actions. The reasons for the seemingly blind pursuit of the objects become clearer over time, as the true implications of the discovery and what it means for humanity as a whole are revealed bit by bit. Meanwhile, there's non-stop action as the tension builds and builds. 
 Sleeping Giants is really a geeky delight. For people into science stories, this is a good one. It involves decoding never-before-seen language and technology and recreating a device without knowing what its purpose is. For those who enjoy action and thrills, there are plenty, including military expeditions and mad escapes. For those into medical thrillers, there are biological experiments and humans being subjected to all sorts of studies, willing or not. 
 On top of all that, the characters are just plain fun. Kara is especially terrific -- and maybe it's the combination of her name and being a pilot, but I couldn't help picturing her as a modern-day version of Starbuck from Battlestar Galactica. 
 Sleeping Giants is already being developed as a movie, and I can easily imagine it being great. Meanwhile, the second book in the series, Waking Gods, is scheduled for publication in 2017 (and believe me, I can't wait to see what happens next.) 
 You know when you read a library book, finish it, and then realize you need your own personal copy? That. 
 Sleeping Giants is a terrific read. Check it out!
