My 9 year old son likes The Hardy Boys - though he had to be coaxed into trying them at first - I don't think they grab as quickly as today's books do - slower intro. But, I'd tell him to read 5 pages and see how he liked it. Now, he reads them on his own. I read both series as a girl - think boys could like Nancy Drew too. Though I hate all the references to Ned in it
