I would recommend Ban This Book by Alan Gratz because it provides a realistic vision of what might happen if kids have their favorite books banned from even being seen. My favorite book would have to be Calvin and Hobbes.
Any James Paterson book is great. I'm currently reading 3 Women Disappear, and it's really interesting so far. I also read The Book Thief and I loved it. For a book by him specifically I would recommend I am the Messenger. My favorite book was probably Cinder by Marissa Meyer.
