for your son:
The Thief Lord
Inkheart series
The Hunger Games series
books by Chris Crutcher
some older standbys, such as Lord of the Flies, The Chocolate Wars, A Separate Peace. these books, and others like them, tend to be viewed as "school reading" books, but they all have male characters as the protaganist, and are very good stories. they focus on some type of struggle that most early teenage boys can relate to, even if the situation is a bit out of the ordinary.
for you:
if you like Twilight, try the Charlaine Harris Sookie Stackhouse series. they are the "adult" version, and IMHO, a better storyline. these are the books that the HBO series True Blood is based on.
if you're in to chic-lit/fiction, try books from Jennifer Weiner, Jennifer Crusie, Sophie Kinsella, Ceclia Ahern, Katie Fforde.
if you like more substance with your books, check out The Thirteenth Tale, The Tale of Halycon Crane, books from Lori Lansens, Elizabeth Kostova. i also recommend The Memory Keeper's Daughter and The Little Book.
if you like thriller/procedural/lawyer/cop type stuff, books from Lisa Jackson, Nelson DeMille, Patricia Cornwall, and Richard North Patterson are good bets. oh, James Patterson also.
two more thoughts for you: check out this website, www.goodreads.com it's a site devoted to ideas for reading and discussing what you read. you join, just like here, and you can browse book lists, track what you read, make recommendations, review books, and join book groups. it's an awesome site.
secondly, see if your local library gets the publication BookPages. if not, go to www.bookpage.com This is another great resource, it previews new and upcoming books, but not just from the NYT Bestseller lists. it covers all genres, including YAL and childrens.
sorry if that's a bit much, i'm a voracious reader, and have tons of suggestions and thoughts on the topic. plus, i'm an english teacher by training, so it's a bit hard to escape.
Happy Reading!
