Storm of Souls (Paperback) (ISBN-13: 9781961138186)

Grimm here, again. You've heard how Crown of Bones went sideways. I'm in hiding and my friends are scattered. And you know the demon doing the scattering is also hunting us all.

The Dead Zone still looms ahead of us, and Sabnock still bars the way. As bad as the demon is, we've discovered something worse. There's a bigger, nastier scheme at play.

Somehow we have to survive. Somehow, we have to strike back. Either around the demon, or through him.
