DS (at the time about 12) went from virtually reading no fiction to reading quite a bit after I visited the above site and spent a fair bit on second hand books on amazon. A few were rejected after slogging through a few chapters. But loads were hits and were part of a series so that helped sorting out the next batch to buy.
I think I started with The Hunger Games and went from there. Is there a book he has read (or as in our case...or film based on a book) that he liked that you can use as a starting point ?
