Her invitation to join the Peace Force could not have come at a better time. Harriet Walsh, 21, has just spent the past two years caring for her sick aunt. Now she's alone, with no job and no prospects, and she's about to be evicted. The Peace Force is an intergalactic crime-fighting organisation with a fearsome reputation, boundless resources, and legions of well-trained officers. Harriet doesn't care about any of that. To her, it offers a steady job with real wages. But why is her invitation printed on the back of an old junk food flyer? And how come she's never seen a Peace Force officer? With the crumpled invite in hand, Harriet heads for the local Peace Force branch... and discovers there's a whole lot less to the famed organisation than she expected. What's more, they desperately need her help!
