I'm thinking of a relatively new kid's chapter book...please help!?

[Coolest Person Around]

Well, I was thinking of this book I read before, but I have no idea what it's called. I can explain many parts of it though...but it might seem a little jumbled. It's I guess a fantasy book, it's fairly large, I think it was published about a year ago or so.

So, there's this boy who's a foster child, and at the place where he stays, the people running the home name all the kids after what day they were brought there. He also had a bear, who was his best friend..and at one point he writes a note to the police station saying he can stop these dogs that are like barking or something. And he meets this fairy thing, who's really happy, but she's in a cage at an evil circus, and somehow he frees her. Then they both ride on a tiger, the teddy bear comes to life...there's a bad man running the circus, and there's a golden ticket talking about this secret city place, like the land of laughter or something and the ticket is on the cover of the book, and I think it's also the name of the book.
Sorry I didn't have enough space to finish...the fairy is like, lighter that a feather, and I think the boy meets with this gang and they play some kind of game. Sorry this is such a wierd explanation! If anyone can figure this out, thanks SO much in advance!!
