Seventeen-year-old Janelle "Ellie" Baker survives in an Ilori-controlled center in New York City. Deemed dangerously volatile because of their initial reaction to the invasion, humanity's emotional transgressions are now grounds for execution. All art, books and creative expression are illegal, but Ellie breaks the rules by keeping a secret library. When a book goes missing, Ellie is terrified that the Ilori will track it back to her and kill her. Born in a lab, M0Rr1S (Morris) was raised to be emotionless. When he finds Ellie's illegal library, he's duty-bound to deliver her for execution. The trouble is, he finds himself drawn to human music and in desperate need of more. They're both breaking the rules for love of art—and Ellie inspires the same feelings in him that music does. Ellie's—and humanity's—fate rests in the hands of an alien she should fear. M0Rr1S has a lot of secrets, but also a potential solution—thousands of miles away. The two embark on a wild and dangerous road trip with a bag of books and their favorite albums, all the while making a story and a song of their own that just might save them both.
