All in all I really recommend reading these books because Book 1 is just sheer awesomeness and if there would be a rating with more than 5 stars on goodreads.com I'd give it a loooot more. Suzanne Collins is a remarkable writer and knows exactly how to keep a reader glued to a book, her writing is great and she knows how to build up the action so you just can't keep away from reading the books! Catching Fire, too is a great book, not as good as the first one but still satisfying. Even though I'm not the biggest fan of the third one, I'll tell you that you just can't help yourself: You have to read it because you SO want to know how it all ends and if you did I'd love for you to come back here and tell me what you thought of Mockingjay and on what parts you just can't agree with me. :)
