Salla Simukka’s 2015 As Black as Ebony is the third and (if trilogy is to retain any meaning) final book in her Snow White Trilogy1.
Lumikki Andersson has returned from a diverting summer holiday in Prague to her parents and home in Finland. Her attempts to lose herself on the stage and in the arms of her new boyfriend Sampsa are doomed before they begin. She is haunted by the mystery she encountered in Prague: how can an only child like Lumikki have had a sister? Why can’t Lumikki remember her? Why are there no photos of the sister? Why have her parents never mentioned her?
And, of course, there’s the lunatic stalking Lumikki.
