Jourdaine Troyce is the commandant of the Guardians, her entire life spent training to kill, literally, anyone that poses the slightest threat to her emperor or the royal family. Killing is as natural as breathing.
Ambreen Prins is a pacifist by nature, killing only as a last resort as she and her young companions fight against the tyranny of the emperor.
Rowan Shayne is the captain of an Intergalactic ship crewed by all the misfits the Fleet can't put anywhere else. They aren't expected to do great things. They're not even expected to function well enough to do their jobs.
Alec Travers is one of the best fighter pilots the Fleet has ever seen, especially when flanked by her two closest friends, creating what they call The Furies. But being posted to Captain Shayne's ship of misfits, out where there are no enemies to fight, is stifling. All she and the other Furies want is to get out there and take down the enemy. Whoever that enemy might be.
Heartbreak, treachery, evil, and the need for justice bring these four together on an adventure to discover the gift of the Redeemer, and the heroines they are destined to become.
