Empowering time travelers to communicate across decades, an eager and gifted temporal engineer develops a secret mail drop, hidden in plain sight on a university campus. Codename: the Timeslot. A charismatic physicist and a focused, revenge-driven hacker go to daring lengths to escape the man who murdered their best friend and fiancé-his boss. A grieving musician in search of closure uncovers her late father's notebook, written before she was born but, impossibly, dated twenty-five years in the future. Generations later, another engineer, brilliant but disorganized, struggles to repair the abandoned Timeslot equipment after years of disuse. Her unexpected discovery draws this disparate group of men and women into a cascade of events which echo across a century of recent-past and near-future history. Journals from five intertwining lives, Black, White, Asian, queer, straight, disabled, and not, blend time travel with mystery, revenge, found family, vintage music, sci-fi references, and even a little romance
