Behind every locked door is a secret waiting to be told, some more dangerous than others. Ancient people unknown to the outside world, on the brink of war with evil. Oblivious to her people, one woman sees the signs, history repeating itself. Domina has fought this evil before and won, but now she's racing to find clues, trying to prove to the elders her gut is not lying. All while training an annoying fledgling that always seems to be in the wrong place at the wrong time. Just when she thinks nothing else can go wrong, The Guard takes over her investigation. Problem? The leader of The Guard is an old flame, Rowan, whom she hasn't seen since their wedding day.
