Hard to narrow it down... I have so many favourites!
But for fiction, everyone should read Fahrenheit 451 by Ray Bradbury and The Fault in Our Stars by John Green. Awesome reads.
I love the author Douglas Coupland. My favorite book of his would be - Generation A, all families are psychotic, and player one. I would recommend generation A to all grades as well as all families are psychotic, but player one is more for older students. Generation A is about the dissapearance of bees in our future and then all of a sudden 5 people around the globe get stung by bees years after they've disappeared. My second favorite book lists are historical fiction of biographies - I Am Malala, Louis Riel by Chester brown, The Snow Child, Me to We, etc. I would recommend these for ALL students!
The unwind series are amazing books about a dystopic society. The fault in our stars by john green was one of my favourites. That's all I can think of right now :)
Delirium was really interesting, it's about how at eighteen everyone gets the cure for love, it' sevruga similar to the Uglies series.
over the sumer i read very little "books"... I have started reading daughter of the centaurs. so far it is a very good book, i would recommend this book to a person who likes fantasy, its about the last human girl, found by the centaurs and taken in as there own, is she the last human girl? need to read to find out the answer.
i read chickion soup for the teenage soul . and they are short little storys about people who were in school and who had a bad sicknes and in the end there problems were solved they got better .
