Looking for good new manga

I've read through as many books of Case Closed and Bleach that I currently can, so I was wondering if anyone would recommend something, please include your reasons as to why you think it's good, and maybe a light summary as to what it's about. Thanks for any ideas.

Well you know that I am going to recommended One Piece to you. It is a great series because it has the right balance of action, comedy, drama, and all that stuff that makes it good. It even has a unique art style inspired by the creator of Dragon Ball (Z) himself.
Basically it's the story of Monkey D. Luffy and his quest to become the pirate king by finding the legendary treasure know as one piece. He starts off by gathering a crew and going on an adventure, but he encounters many strange pirates and government officials on the way. There is no set way to describe it, but once you start reading, I am sure that you will enjoy it.

Don't forget to add Fairy Tail to that list. It is a really amazing and unique story, despite having some elements of Rave Master in it.
