An alien crashes deep into the oil fields of New Mexico with a mission: he has eight hours to find the one woman on earth who can save his species. Together they discover that in order to save his world, they must first save ours.

After the shocking discovery that The Mission is far more complex and dangerous than he believed, and the only human who can guide him abandons him to protect her family and her sanity, Faraday must go it alone, unaware that he's suddenly on the radar of a CIA agent.

Justin finally accepts that Faraday's mission is the next step toward her own long-abandoned dream; with the addition of a wild card risk assessor, they embark on a journey that takes them further than they ever imagined.

Secrets emerge when Faraday, Justin, and Hatch get thrust into the world of Big Tech; Hatch and his sister reconnect after years of estrangement; the CIA tightens its grip as Faraday comes face-to-face with a consequence of becoming human.

Faraday discovers his inability to decipher Newton's blueprint for the machine; the mission grinds to a halt until Faraday uncovers long buried truths about the relationship between Earth and his home planet.

In what we would call a love letter to his wife on Anthea, Faraday shares with her the complexities of becoming human.
