Peace is priority in a world of Immortals. In the city of Neapolis, memory regulation is the key to a peace. After all, no one would pay to hold a grudge or remember an argument, if other memories are more precious. This is what Cy has been taught to believe. But no amount of money can bring back the memories of who Cy was two centuries before, before The Sickness. That is the truth of life for every Immortal. When Cy suddenly starts remembering her life from before The Sickness, there's a target drawn on her back. Clearly, this type of memory is a death sentence. So, Cy escapes, vowing to retrieve everyone's lost memories, and one day return to destroy Neapolis. But does Cy really want to know who she was before? And at what cost?
