The Hunger Games by Suzanne Collins Red Rock Mysteries series by Jerry B Jenkins and Chris Fabry Between Shades of Gray by Ruta Septeys The Lost Books series by Ted Dekker The Circle Trilogy series by Ted Dekker The Rayne Tour series by Brandilyn and Amberly Collins
anything written by mark twain! start the fine young man off with "the mysterious stranger"...a not so short 'short story.' it's the greatest short story I've ever read. it's perfect for a twelve year old and their fantastic imaginative mind. I have been hooked on mark twain since I was about 9, over 50 years ago...;-)
Depends on what they like. If they like comic books, then buy them books that are about superheroes. I totally love books like that, even though I'm a girl. But if they like humor, then try Diary of a Wimpy kid. That's funny.
If he likes mysteries and/or ghost stories you could try Mary Downing Hahn's books. Some of her books are, Wait Till Helen Comes (freaked me out), Time for Andrew, Deep, Dark, and Dangerous, Stepping On the Cracks, The Ghost of Crutchfield Hall, and Closed for the Season.
Wonder is a great book a 12 year old could relate to this book it is fiction. Between Shades of Gray is about world war II and a family going through it. Harry Potter is a good one if you love fantasy.
In most books you need to read more than the beginning to get into a good book.
