Mackenzie Jo Phillips returns home after a hard day wanting only a hot bath and a cool glass of cheap wine. Instead, she finds an alien in her garage…again. Mack—she hates Mackenzie—is a retired alpha agent of the Galactic Enforcement Agency. Mack was formerly assigned to region nine, which is a galactic backwater way out on the edge of the galaxy that happens to include Earth. Most GEA alpha agents retire early, which is a GEA euphemism for dying on the job. Mack took one too many blaster-cannon shots to the guts, wound up in a meditank once too often, and decided to retire to Southborough, a picturesque New England town outside Boston, while she still had all her parts. Mack is retired. She’s not supposed to have an alien in her garage. This is not good. Either the GEA has reactivated her, which would be bad, or the alien is here on his own hook, which would be, well, bad. Mack has a hard choice, let the galaxy take care of itself or help the alien and do what she does best: kick ass and take names.
