Waking Gods

 Waking Gods by Sylvain Neuvel, 336 pages

As promised, book 2 of the Themis Files. This book begins about a decade after the first book. Our pilots are married and have been enjoying their time functioning as goodwill ambassadors for the planet. Unfortunately, it quickly becomes obvious why the Earth Defense Corps is technically a military organization when another giant robot appears in London and causes massive casualties. Even more so when giant alien robots appear in cities all over the world. A single outdated robot won't do much against an invasion, so it is absolutely vital to figure out what they want, which proves to be a difficult problem for Earth's greatest minds. 

Although a little less compelling from a character standpoint, I found the mystery of this book to be very intriguing. I think this was a great continuation, and it did a really good job continuing the questions of the first book while exploring more global consequences as the secret of Themis is out. A very satisfying sequel, and I again strongly recommend the audiobook.
