Very fast-paced and engaging. The mixed media format of the story-telling was quite creative and smartly done (though some of it must have been for aesthetics). The only fault with the story is the messaging dialogue, which I found cringing at times, both the "text-speak" and CONSTANT quipping (like Tony Stark talking to himself) between the teenage main characters, and then the occasional subtle sexting between higher officials or whatever their titles were. It sorta downplayed the tension and the severity of the actual plot. There were other occasions of humour I really enjoyed, which was more observational through the reports and other characters. Also I want to know more about McCall. She was cool
