Help with a book title?

So my story is going to based on a circus, werewolves and romance. I don't want to give too much of the storyline away (pretty much because I haven't thought that far ahead) But there is going to be action and fighting, and tears and all that..
I've thought of having something with 'attraction' in it because of circus attractions and the attraction between mates but I don't know..
Help please?
