Cassandra Clare and D.J. Machale
They both write books (The Mortal Instruments, Pendragon) that have a teen protagonist, even though the genders are different in the two series. Cassandra Clare makes Clary very average, which is much easier to relate to than someone who wasn't. Pendragon's protagonist is Bobby, and though he's a boy and I'm a girl, I can relate because he speaks in ways of a teenager, not an adult. He admits when he does things wrong, which is odd to find in books. Usually the protagonists do nothing wrong, which makes it less believable.
