Entire worlds have gone dark, and the vast fleets of the galaxy are mobilizing in secret. Leon Victor and his girlfriend Rachel Case are making a life together on the planet Eve, doing their best to avoid war. However, war might come looking for them. Leon Victor is a Ronin for the Jackal Pack Mercenary Legion and no stranger to war, but after witnessing the inexplicable on the planet Aethaleia, he's not even sure who, or what, he'll be fighting. While Leon and his friends have built a career on overcoming the unexpected, he has a sneaking suspicion that this time will be different. He is right: those friendships will be tested, empires will fall, and the galaxy will never be the same.
