Young Justice CYOA

From the introduction: Welcome to the world of Young Justice! Designated as Earth-16, you will find yourself 12 hours before the events depicted in the first episode. From there, events will unwind in a way that before the day is done, you will be given the option of joining the Team - so long as you don't do anything too evil before then. If you refuse, and you're interesting enough, other opportunities might come to life.
