Books that I´ve read in my teenage years

When I was at the school, I´ve read a lot of books for a language class, but only a few of them I´ve liked so much.
The first book that I´ve read it call "El Túnel",  written by Ernesto Sábato. This book it represent basically the hardest feelings felt by a person in a bad moment. when someone feels empty and alone this book may you grown up and change some thought about the reasons for living. I recommend this amazing book because after read it, I appreciate the oportunities and little details of the live, so could you too :).
The second book that I´ve read it call "Juventud En Éxtasis" written by "Carlos Cuauhtémoc Sánchez" this is a special book because it shown me what happened with the change between the childhood and teenage years. It´s a very difficult book, but I recommend it, because it teach good lesson for how survive in a crazy  and curious teenage life. :)
Personally I think that this book teach me the importance of how the life can change if the people don´t make the right decision.
