I needed something a bit lighter after some more serious Nonfiction lately, so I picked up the next book in this YA action series. It took me a little while to place everything again after a long hiatus, but I loved seeing Sam reunited with the group, and for a slower start, this one definitely ended with a bang... reunions, betrayals, some massive plot twists and predictions about the future, and a few new players with questionable motives.
