I must say, that I am teenager, too. I know, that people don't read in this age, but I love reading. It's my hobby. I haven't read every book for teenagers (just for now), so I can't give you completed list of the best, but I'll try to choose wisely.
Why? Because it's classic, of course. The magic world of Harry Potter is awesome. I love this one and You will love Harry Potter too. I promise.
By the way, there are lots of cool characters. What about Luna, Tonks or Proffesor Trellavney? Soo crazy. But we all love them.

The Hunger Games
Of course that THG are here, man. This is such a great story, You know? I think that there are lots of reasons, why. In these books/films you can find love, courage, danger and also a little bit of hate. The main character Katniss is very courageous young woman, and she shows us, that women are at least as good as men. But she has a cool boyfriend, you know. Oh, there are just two tips of people - team Gale or team Peeta. Which one are you? How could I forget?! The best couple of all series is Hayffie - Haymitch and Effie. I love them. I just love them. And I will. Forever.
Looking for Alaska and other Green books
What can I say here? You just love them or hate them, nothing between. And I must say, that John Green is a perfect writer. Thank you, John Green! You made my life better :).
I think that it's all. Enjoy time with book, guys!
