No Science Fiction? Good luck. Science fiction is the best hook for boys.
I recommend Ender's Game - the best book for boys that age ever written. It is Science Fiction.
Kite Runner was mentioned, great book.
Sincey you mention the boy in the strped pajamas. Here's more Halocaust materials
My son loved the Book Thief. Milkweed by Jerry Spinelli is also good.
Steal a Pencil for Me is a love story written in letters by two survivors. (it is also an indpendent documentary)
My son is a voriacious reader. He likes History based books. Right now he's reading a book about what would happen if certain events in history never happened (ie, the Enola Gay never showed up)
What is the name of that book-it sounds interesting
Is required Grade 12 reading so that is out, unfortunately ...
