The Gargoyle, Morganville Vampires series, Practical Magic, Scar Tissue, Tuck Everlasting, Hamlet, Paper Towns, and Howl's Moving Castle.
Harry Potter (naturally), Lord of the Flies, The Hunger Games, A Song of Ice and Fire, Lord of the Rings... and I also love a number of non-fiction works as well, namely books of useless trivia and facts. There's nothing quite like gaining pointless knowledge ;)
Favorite books? I know you've gotten it a lot, but The Perks of Being a Wallflower. The Last Unicorn and The Virgin Suicides are some of my other favorites, along with White Fang, World War Z, The Egypt Game (kinda for kids, but it was my favorite book in grade school), Godless, and for guilty pleasure the Flowers in the Attic series. They're So Bad they're Good.
Bridge to Terabithia
The Tomorrow Code. A Mango-Shaped Space. The Miraculous Journey of Edward Tulane.
Favorite book of all time, no matter what, will always be To Kill a Mockingbird. Ever since we read it in school, I couldn't stop loving it. Bought my own hardcover, decorated copy and I read it every so often, thing's gettin' worn out now from being used so much. LOL <3
Hahaha can you believe I still haven’t read it? I’ll get to it someday :]
Tamora Pierce's Tortall series, Graceling by Kristen Cashore and pretty much anything by Charles de Lint.
The Secret History by Donna Tartt. I recommend it to people at every opportunity.
Adios, Nirvana by Conrad Wesselhoeft
the Harry Potters, Narnia, One Flew Over The Cuckoo's Nest, The Perks of Being A Wallflower, It's Kind of a Funny Story <3
I have to agree with all the John Green suggestions. Markus Zusak's books are marvelous too. ;D
