All of these books are great:
Maximum Ride Series - James Patterson
Book 1: The Angel Experiment
Max had avian dna grafted into her before she was born, by sadistic scientists. Now she and the five others in her adopted family have wings, and they can fly. They are on the run from the scientists who will do anything to get them back. To make things more complicated, they are also being tracked by another of the scientist's experimental breeds: part human, part wolf, with a taste for flying kids.
These books are sooo good! I read the first one in 2 days (422 pages)
The Hunger Games - Suzanne Collins
In the future, in a place that used to be known as the U.S. every year, 24 teens are forced to participate in a "reality t.v. show." Only the winner lives. I loved this book. It made me cry.
Uglies - Scott Westerfeld (and anything else by him)
In Tally's world, when everyone turns 16, they receive an operation that makes them beautiful. When Tally's friend decides to run away and avoid the operation, Tally is forced to follow, and on the way, learns a horrible secret about being beautiful. Great book! Scott Westerfeld is awesome!
You Don't Know Me - David Klass
Told from inside the mind of a boy whose mother's boyfriend abuses him. It's funny, but deep. A really good book.
Unwind - Neal Shusterman
When the government outlaws terminating pregnancies, they come up with a new solution to this problem. Children between 13 and 17 can be "unwound," where their body parts will be donated to those in need. This story is about three kids who are trying to fight the society that would "unwind" them. This was one of the first really great books that I'd read in a looong time. I would soooo recommend it.
Thirteen Reasons Why - Jay Asher
I didn't love this, but everyone I know did. When Sarah Baker commits suicide, she makes tapes, which she sends to all of the people who affected her decision. It's told from the POV of the boy who had a crush on her, and he's wondering why he received a tape from her. What did he do that would make her want to die?
Generation Dead - Daniel Waters
If you liked Twilight, I would recommend this one. It was a really good book, but it didn't rip off the vampire idea. It is definitely worth reading.
Gone - Michael Grant
When everyone 15 years or older disappears, kids go crazy. Bullies rule, and no one knows what to do. Not only that, but animals are mutating, and kids are developing special powers. (I know it sounds kind of dumb, but it really isn't, it's soooo good!)
Skinned - Robin Wasserman
Lia had a perfect life until she almost died in a car crash. Her body was destroyed, so her mind was downloaded into a new body that only looks human. She will never eat, feel pain, or age again. Society is against her, and everyone like her. It's a pretty good book. You should read it.
Hacking Harvard - Robin Wasserman
Really funny. Three kids make a bet to see if the can cheat their way into Harvard and prove the flaw in the admission system. It was a good book.
Can't Get There From Here - Todd Strasser
I loved this one. It's about a tribe of teens living on the streets of New York.
The Year Of Secret Assignments - Moriarty
This one is laugh out loud funny. It's about a group of penpals in different schools. It's written through their letters and emails and journal entries. It's sooooo funny.
Godless - Pete Hautman
A group of kids decide to worship a water tower. Need I say more? Funny book.
Going Nowhere Faster - Sean Beaudoin
Most hilarious (random) book I've ever read.
Pretty Little Liars - Sara Shepard
Mystery book. Four girls begin to receive threatening messages from their old best friend. Who is supposed to be dead. It was definitely hard to put down. Kind of scary.
The Outsiders – S.E. Hinton
This book is sooooo good! Read it!
Tex - S.E. Hinton
If you liked The Outsiders, you'll like this one. It's not quite as good (nothing could be) but I really liked it.
Truancy - Isamu Fukui
When school rules a child's life, along with cruel leaders and teachers, a group of kids try to fight the system. Tack thinks he know what side he's on, especially when someone he cares about is hurt in a crossfire between the two sides, but after some time, he's not sure anymore. I liked the book. My friend wouldn't read it because it was too violent for her, but I thought it was good though. (but I didn't like the ending)
