Fifteen years ago, siblings Coil and Cassiopeia suffered an incident in the woods behind their family home. An incident that neither of them are willing to remember. Something that nearly killed Cass and left Coil accused as her abuser. An act that robbed young Coil of his artistic potential yet boosted his little sister into an almost overnight sensation in the art world.
Now, fifteen years later, the self-exiled Coil has come home to deal with his world famous sister as she suffers from sundowning; severe and violent personality shifts after the sun sets. Coil s reluctant loyalty to his family is rewarded with an unexpected return to his artistic roots, as he wakes each day to find he has painted a brilliant but disturbing masterpiece in his sleep.
