My oldest is a boy, almost 20 and in college, and a voracious reader. Even at school he has a fiction book going most of the time to give him a break from his engineering course work. As a kid for him I used a list put out by a defunct classical Christian email group. The list was called The 1000 Good Books
http://www.classical-homeschooling.org/celoop/1000.html and was divided by reading level. I went through that list and would read books to both my kids at the time (boy and girl), and by the time they could navigate a library on their own, I'd mark books I wanted them to read, and they'd choose from the list. During our read aloud times I'd alternate a 'girlish' book with a 'boyish' book. Together we read Charlotte's Web, The Hobbit (and all three LOTR novels), The Secret Garden, Railway Children, Understood Betsey, Boxcar Children (original set), Happy Hollisters, Henty books, you name it. But he did tend to pick boy books on his own. Now his genres of choice lean to science fiction, adventure, spy stuff--very masculine type books. But my daughter is not a great reader. She is now doing more of it, but isn't into girly type books, although her most favorite is Pride and Prejudice. But she has picked up so much from our reading of good literature as a family. She likes to write stories, and definitely can turn a phrase in her writing, as a friend who has done some writing classes with her, says. My point, if I have one, is to just concentrate on good books. If your dh balks at him reading 'girlish' looking books on his own, save them for family reading time. A good book is a good book. What's important is that they are hearing/reading a well written book, not what the cover looks like, or whether the main character is a boy or girl.
Now that I see the booklist is still available online, I think I'll pull it out for #3.
