Jade moves out of her safe commune, inhabited by humans merged with inter-dimensional beings, and takes on a mission of observing and analyzing human behavior in the outside world. But questions about who she really is and what she sees quickly overwhelm her. Why are she and her closest commune friend considered so special? Although most of the beings from her commune, nicknamed Extras, have access to magical powers, why are hers more varied and potent? At a Halloween party, a group of college kids, who she learns are a different type of Extra, trick her into a torturous experience. Why did they specifically target her? And then a guy named Adam shows up, asking questions about his brother who, he says, was brainwashed by a controversial cult. Who is Adam, and what does he want? Jade concludes that a terrible risk is growing for her entire community, and nothing is more important than finding answers.

Extras explores and personalizes universal struggles ingrained in the human experience such as: the love of power vs the power of love, the instinct to control outcomes vs the embracing of impermanence, and always, the endless quest to be kind to ourselves and others.
