Since the above post recommended The Hunger Games after you said that your son had already liked and read the series, let me suggest you some additional titles:
The Roar by Emma Clayton (2009)
In the future, civilization is protected by high security fences. A deadly plague has infected the animals, turning them into vicious killers, but Mika, the main character, begins to have his suspicions once his twin sister mysteriously disappears. The Roar combines dystopian elements with science fiction and suspense. There is also a sequel, The Whisper, which is equally good.
Gone by Michael Grant (2008)
Every adult vanishes unexpectedly, and what happens in the confusing aftermath is even more horrific. Gone is an action packed novel turned series that many of my students not only enjoy, but fight over who gets to read the next book.
Black Hole Sun by David Macinnis Gill (2010)
This novel reminds me of Ray Bradbury's The Martian Chronicles, only Black Hole Sun actually has a suspenseful, enjoyable page-turning plot. The novel takes place on a polluted, festering Mars. It has sort of a Firefly, space cowboy feel to it that makes it a lot of fun to read.
The Eleventh Plague by Jeff Hirsch (2011)
Post-apocalypse, humanity has been shattered by a devastating strand of influenza, and the novel focuses on a community that struggles to deal with the aftermath. The great thing about this novel is that it completely suspends disbelief, making Hirsch's scenario about the end of civilization as we know it completely realistic and believable.
*The best thing about all of the above-mentioned novels is that they all have young teenage main characters that most young adult readers can really identify with and feel more relevant and current since all the titles have ben published in the last five years.
I would definitely recommend The Hunger Games series of books by Suzanne Collins as they have elements of several different genres of literature. Most boys these days like adventure, drama, mystery, and science fiction, all of which were found in the three books. And, there's just enough humor and romance in the stories to make them interesting without being boring and mushy.
My 13-year-old son also doesn't like to read, but had to do summer school reading in preparation for his 7th grade Language Arts class. The book he was assigned to read was Huckleberry Finn by Mark Twain. I had never read it myself and decided to join him in his reading. My son's teacher suggested getting an audio book to listen to as we followed along in the text, and it turned out to be quite enjoyable. I highly recommend it and it's companion book, Tom Sawyer.
These five books should provide ample, diverse material for any boy to read.
