The royal princess, Victoria Smythe-Peterwald, was raised to do little except looking the part and marrying well. But when her brother, their father's favourite and heir, is killed in battle by Kris Longknife everything changes. She is the daughter of their lifelong enemies and Vicky vows revenge, but skills are more suited to seduction than assassination and her mission fails. Her father sends her to join the Navy to get some much needed military training. Now Vicky is part of a whole new world, where she must learn to be ruthless and deadly, and she needs help from Kris.
