A Hunt in the dark is a short story about the ascension of Sammael to grand master of the Ravenwing, and how the previous master, Gideon, died. Sammael will be put into interrogation in the depths of The Rock... and things will happen.
It is truly a quick read, interesting but... alone feels too small to be worth 3€. Better to wait for a compilation.
