I really really recommend this book, this book is actually a very interesting predictions for the future Earth. This book is based on statements of what it'll be like in the future when the aliens attacked Earth. My favorite part of the book is actually their slogans, Wave 1 - Darkness, Wave 2 - Destruction, Wave 3 - Infection, Wave 4 - Invasion, The 5th Wave - We fight back. I thought that their slogans are really cool and it's very interesting about how they came up with the idea of making it into 5th wave total but not more or less. To me, I'll definitely not wish for the aliens to one day really invade the Earth, it'll be very sad and sad since they bring people disaster and break apart both their heart and mind, they tear us apart from the inside. I feel sad and surprised about finding the death of her mom, I didn't expect that the author will talk about her mom and that her mom actually died.
