Eastern Standard Tribe by Cory Doctorow

Set in a near-future world where people align themselves with tribes based on time zones rather than geography, the story follows Art, a UX designer who is secretly working to sabotage his employer for the benefit of his own tribe. As Art navigates the complexities of loyalty, love, and betrayal, he finds himself questioning the very foundations of his identity and the societal structures that dictate his life. With a blend of humor and insight, the narrative explores themes of technology, trust, and the human need for connection in an increasingly digital world.
