Just like the first part of this trilogy, this book is very entertaining because of its fast-moving plot, a quick read because of its short chapters, and a tad deeper than some other sci-fi books (but just a tad). Just what I needed as a literary palate cleanser after two heavy books I had read back to back (sorry Mr Neuvel), captivating and exciting, and with a terrible cliffhanger that made me get the third part of the trilogy as soon as I could.
