[Belmont2500]

Besides me, has anyone else heard of Margaret Peterson Haddix's Shadow Children books, if you haven't, its a series of seven books(Among The Hidden, Among The Imposters,Among The Betrayed,Among The Barons,Among The Brave,Among The Enemy and Among The Free) and it takes place  in this world where food is scarce because of a famine and the most horrifying part - third children are illegal(what have we become), that's right, in the world of Shadow Children only two children are allowed per family and who takes care of all the criminals and "illegal" third children, a force known only as the Population Police and they aren't friendly, most of the protagonists differ from book to book, in most books its Luke Garner AKA Lee and so on.
