The fate of thousands of lives rests on electromagnetic teeth, alien cattle, a borrowed lasso, and the herding instinct of one very determined space dog.
Sunset is a sapient Miniature American Shepherd who loves two things above all else: herding space sheep and going fast. When her old friend Carter, a newly retired Newfoundland Dog Space Marine, arrives for a visit just as shearing season peaks, the reunion turns serious fast. A rogue asteroid the size of a city block is locked onto a collision course with Boogaloo Station, and someone, or something, put it there on purpose. Saving thousands of lives will take every skill this unlikely crew has, and a few they will have to invent on the fly.
Good dogs save the galaxy. This is how.
