Blood and Ash #6.5The main Blood and Ash series should be read in publication order. The Flesh and Fire series, which includes 'A Shadow in the Ember' and 'A Light in the Flame,' serves as a prequel series set centuries before the events of Blood and Ash, and can be read either before or after the main series.
Yes, the Flesh and Fire series is a prequel to the Blood and Ash series, exploring the origins of key characters and events that are central to the main storyline. While set in the same universe, it focuses on different protagonists and an earlier time period.
As of my last update, there is no confirmed film or television adaptation of the Blood and Ash series.
