Coup de Grace (Paperback) (ISBN-13: 9781732247741)

In that other world, I found a mysterious girl. Her life had been stolen to power a demon's magic.

And I left her behind, bound to that demon.

Now nothing else matters to me.

Not my graduation.

Not Grace's excuses or the politics of summoners.

Not my friends, and not my foster family.

I abandoned her, leaving her enslaved.

I will burn everything to fix that.
