Idris is an apprentice at the Rose Assassin Academy, the smallest but most elite of the four major assassin clans. Every year they only accept the six highest paying contracts, and in their centuries long history, they have never failed to complete a single one. For a long time, assassin clans have been governing the balance of the world. But now, the balance is beginning to shift. With one strange event after another, one tragedy after another, there seems to be something coming for their throats. Idris and his friends must embark on a journey to protect their clan, their family, and to unravel the mysterious tides crashing against them.
