   Summary

   Harry Potter is smart. And handsome. And smart. And extremely handsome. Every girl wants him, and some boys too. But Iris Potter, his twin sister, knows better. She knows what he really needs, what he really likes. And she will not let anyone have her big (older by eight minutes) brother, not as long as she has anything to say about it.
