The Stronghold 2: Immortals

Pepper returned and life resumed normal for everybody at the Stronghold; apart from for Shaade, that is. With his husband never coming back and lies pressing in on him from every side he can do nothing to escape - until a simple street fight develops into so much more.
Dragged into a world full of confusion, secrets and agents that can't put up with Shaade's craziness the shadow demon must make a final decision; does he go back to his friends or does he continue to break codes? Can he face the people he no longer trusts? Or does he develop his career as a not-so-secret agent?
There's no going back once you've made your choice.

This is the SECOND book in the Stronghold series, or the SEVENTH book in the Super Glitches series.
