Hey there!
So this three part series: The Cost of Peace, also has companion pieces! Kendrene has also written a companion piece to this fic. It starts from the same scenario, has some of the same details, but it totally flips the ABO dynamic on it's head. You are going to want to read it, but please make sure you read the tags first. It's called The Cost of Peace: Sacrifice.
Here is the link to her story on AO3. Enjoy. :)
