umm, can you sugest good action and adventure books?

What kind of adventure books? Does he read science fiction? Because if he does, he might like A Wrinkle in Time by Madeleine L'Engle (an amazing book but the beginning is quite slow). Also, the Mortal Engines series by Philip Reeve is quite good although no one I know has heard of it.

If all else fails, just try a classic like the Thirty Nine Steps by John Buchan (I haven't actually read this one but my brother has and he said it was really good. It's sort of a world war one spy thriller)

I hope that helps.

my suggestions are many.u can prefer on twilight for both romance and actition. dan brown's books, especially angels and demons are a good choice.harry potter series. u may have read it. jeffrey archer's a prisoner of birth is also good.
