Hiromi's life was going nowhere fast, until the day it went everywhere, all at once. All it took was a stolen tube of Pringles, a mysterious inheritance from a mad uncle, and one very, very bad decision. One minute, she's a stressed-out IT worker in London. The next, she's the unwilling owner of a doomsday weapon, the reluctant leader of a crew of cosmic oddballs, and the most wanted woman in the galaxy.
Hunted by fanatical zealots and shadowy government agents, Hiromi must navigate a universe of treacherous aliens, high-stakes cons, and mind-bending technology. She's not a hero. She's a tech support specialist who's good at writing stories and terrible at talking to people. But when you're on the run with a galaxy to save, you have to work with what you've got.
