The book is about a homicide detective obsessed with taking revenge on her husband's murderer, how her obsession costs her everything she has left, and how she ultimately finds redemption by saving someone she loves. The client wanted the cover to convey a sense of something ominous and was not after a literal picture. My aim was to emphasize the contrast between the holiday season and the main protagonist's emotional state. Fog, blurred car lights in the background, snow melting and the drops ominously sliding down the pine needles almost like tears. :-)
