Hey kitties! I wrote the following article for NA Alley and you can read it and other awesome posts about New Adult books and media over on NA Alley! Do You Cosplay?

Being a new adult is all about defining and expressing yourself as individual, and finding your tribe, and cosplay offers participants a way to proudly wave their little geek flags for the world to see.
