Hanna works for the Perpetual Post, the transgalactic delivery service for packages that absolutely have to get there, no matter how long it takes. Guided by her AI Administrator, she travels vast stretches of time at relativistic speeds, delivering messages and objects to the perfect moment to change history. But her latest delivery has less to do with galactic events, and more to do with her own personal history.
