I've been looking for a book that was part of a series. It was about this group of young kids who are really monsters but keep it secret. One of them is a werewolfe and his name is Howie. I can't remember the rest but one of them is a water creature and I think one of them is like frankenstien. They live in Boston. That's about all I know. Hope someone can help! Oh, these are children's books.
