Rachel Stein

"With my biggest mistake laid bare, Rachel didn't miss the chance to seize on it. 'So you had control of this…complex, and you just gave it to her?' Her voice was acid. We hadn't gotten along back in school, and that didn't appear set to change."Rachel Stein is one of the Fire Lake sophomores. She is described as being slender and coldly beautiful with long, dark hair. Rachel is condescending, hostile, sarcastic, and often aggressive, frequently passing all blame to Min Wilder for bad situations.

In the Program
Rachel leaves town the first chance she gets, holing up in a house somewhere in the valley by herself. She also manages to drive her car, a Range Rover, throughout the Program. When Sarah Harden creates a blizzard and threatens to bury the valley, Rachel joins up with the Life-Trading Team and takes joy in receiving lives from Tack Russo by shooting him. She survives the final battle in Town Square and is regenerated with the rest of her classmates. She is the last one to vote to add the eliminated codes to the regeneration process.

Chrysalis
Rachel lives in Home Town after the Program, seeming to take issue with Min's and Sarah's leadership roles. Aboard Chrysalis, she passes all of her tests, claiming somehow that the entire process is Min's fault once again. She survives Sophia's final attack and joins Livingston Colony on Mars, becoming pregnant with the first child of the post-apocalyptic generation.
