After losing her husband and daughter in an all-too-common act of senseless terror, Nina Rogers thinks she might also be losing her mind. Is she slipping because of the tragedy, or is her memory actually failing her? Is she experiencing the same thing her mother did, or is this something different? It might be easy to figure out in a normal person, but Nina is anything but normal. She has hyperthymesia: the ability to recall every minute of every day of her life. As the days go on, she sinks even deeper into madness and knows that she needs to find some answers to what is happening to her before it’s too late. Tragically, the one person who may be able to help is also the man who killed her family.
