NPR recently polled listeners for the best ever teen fiction. The results of their poll indicate that young adult literature is popular not only among teens, but among adults as well. In fact, NPR points out that a "whopping 75,220 voted ..., blasting past the total for last year's science fiction and fantasy poll at, dare we say it, warp speed."
Harry Potter and the Hunger Games trilogy top the list. A bit surprisingly the classic To Kill a Mockingbird is #3. By far, the most popular current male author writing for a teen audience is John Green.
Here's the complete list; you'll find these books and more by searching the library's catalog.
