And some quotes from these books picked by me :-)
“I thought about mistakes I had made in the past. I thought about when things went wrong. And I realized it was never an issue of intent, but of intensity. I was a good guy, recall.” - Inexcusable - Chris Lynch
"I picked up one of the books and flipped through it. Don't get me wrong, I like reading. But some books should come with warning labels: Caution: contains characters and plots guaranteed to induce sleepiness. Do not attempt to operate heavy machinery after ingesting more than one chapter. Has been known to cause blindness, seizures and a terminal loathing of literature. Should only be taken under the supervision of a highly trained English teacher. Preferably one who grades on the curve." - Twisted - Laurie Halse Anderson
"You can love someone so much. But you can never love people as much as you can miss them." - An Abundance of Katherines - John Green
"I am messaging you to say that I love you, and that you're completely wrong about me thinking you're stupid. I always thought you could teach me things. I was always waiting. You're not like the others. You say things that no one expects you to. You think you're stupid. You want to be stupid. But you're someone people could learn from" - Feed - M.T. Anderson
"These are hard times. The world hurts. We live in fear and forget to walk with hope. But hope has not forgotten you. So ask it to dinner. It's probably hungry and would appreciate the invitation."
"In a world like this one, only the random makes sense." - Going Bovine - Libba Bray
"Sometimes I feel like I have walked into the middle of a movie. Maybe I can make my own movie. The film will be the story of my life. No, not my life, but of this experience. I'll call it what the lady who is the prosecutor called me. MONSTER." Monster - Walter Dean Myers
"Sometimes people are beautiful.
Not in looks.
Not in what they say.
Just in what they are."
"I have hated words and I have loved them, and I hope I have made them right.” - The Book Thief - Markus Zusak
"Me? I had no dreams. No longings. Dreams only set you up for disappointment. Plus, you had to have a life to have dreams of a better life."
"Out of sight, out of mind. My philosophy of life in a test tube." - Luna - Julie Anne Peters
"You don't have to know everything in the world. We aren't supposed to. It makes you boring in mixed company if you can't be interested and ask questions of other people."
"All I can think is that I want her more than anything. I want her more than I've ever wanted anything, ever." - The First Part Last - Angela Johnson
"What sexual preference do you hope she has?” “Happiness.” Isn't that cool?"
"Love is a dangerous angel." - Weetzie Bat - Francesca Lia Block
"One's my favorite number. The word won being the past tense of win, and we can all say at the end of the day that we won once again, can't we? Some days making it to the end of the day is quite a victory."
"Just like there's always time for pain, there's always time for healing." - Hate List - Jennifer Brown
"If I were to live a thousand years, I would belong to you for all of them. If we were to live a thousand lives, I would want to make you mine in each one." - The Unbecoming of Mara Dyer - Michelle Hodkin
"You should always be taking pictures, if not with a camera then with your mind. Memories you capture on purpose are always more vivid than the ones you pick up by accident." - Warm Bodies - Isaac Marion
"If this were a fairy tale, this would be the part where the fishboy appears and Diana shoots him through the heart. Because he is a tragic hero, he's our fucking Gatsby, and he lived for his fish and he has to die for his fish." - Teeth - Hannah Moskowitz
