A string of murders that had stumped the police for twenty years. The killer’s calling card? A small bouquet of lilies and dill placed over the victims’ chests.

With no evidence and no way to find them, the culprit is known only as “The Lily Killer”. Luna Winchester is a PI who specializes in cases involving minorities, prejudice and, most of the time, going against the police force.

One thing Luna hasn’t done in years is work in missing person’s cases. But, when she receives strange messages and finds a box at the door of her house, Luna is pulled back into the police work she had turned her back to.

The case is of a young man who disappeared on a road without a trace. The police has decided him to be a runaway, but the person who got in touch with Luna thinks otherwise: Ian Bauer was kidnapped.

Never one to let go of a mystery or risk someone’s life, Luna delves deeper into the case, pulled by the evidence and the weird link the missing kid has to an inactive serial killer. As she follows the trail Ian left, a target is placed on her back and Luna needs to find this killer before he finds her.

Can Luna solve this ten-year cold case when the police couldn't? And can she do it before someone else or herself get hurt?. .
