Molly saves from certain death a bounty hunter who happens to be her ex-boyfriend. Julie dispatches a voracious demon with a piece of high tech weaponry. Charlotte protects thousands of human colonists from marauding artificial intelligences. The women in these stories are from different backgrounds, have different motivations and find themselves in wildly different situations. But they all have one thing in common: when push comes to shove, you'd better get out of their way. Because they are all tough girls.
