HOLY SHIT SNACKS. THIS BOOK IS PHENOMENAL. It grabs you from the very beginning and doesn't let go. Perfectly paced and plotted with puzzles within puzzles and '80s pop culture sprinkled throughout (alliteration ftw). It was a little different than I expected, I guess I didn't expect so much '80s, but by God it was fantastic. I am definitely picking this book up for myself later.
