Hi, I'm looking for suggestions for books to get for my teenage son. He's 14, loves sci-fi, fantasy, adventure type stuff and reads so much we can't keep up with him. He's done all the usual sets, alex rider, twilight, dan brown, cassandra clare, skullduggery, time riders and rick riordan books. We tried giving him James Patterson but he didn't like them, said they were boring adult books.
Just looking for some suggestions as what to buy/ borrow next.
