The 5th wave is so kickass and brilliantly fuses an apocalyptic novel with extraterrestrial elements. 
 10/10 would recommend this book. I loved the character, she really grew on me. I admired her development of strength and devotion to her brother along with the fact that she was so relatable. Also Yancey references periods. YES MENSTRUATION. It was incredibly refreshing to see this book acknowledge female bodily functions - more books should follow this example. 
 The only squabbles I had with this book was that: 
 - It was kind of predictable especially the whole Sammy thing 
 - I didn't like Cassie's love interest and their whole relationship was eurgh
