Witch Summoned. The Hour of Witches, #4

I really need to run when the past comes knocking. Just when I thought my troubles were behind me, who should invade my pub but the same fae duchess who accused me of murder? Now she needs help, but I trust her about as much as I do an unlabelled bottle behind the bar. She wants Trace to use his stolen souls to save the wall that divides the mundane world from the supernatural. On the surface, her plan benefits everyone.
Trace needs a safe place to release the souls, and if the wall falls, we're talking diplomatic disaster. But the risks are high, and failure could mean Trace's death. Not that she's giving us a choice. Although the realm is an incredible place, it doesn't take long to realize there's more going on than the duchess claimed. Something is following us, I have no idea if we can trust our guide, and the amount of magic everywhere we go is testing Trace's control over his guests.
Our window for success is closing quickly, and if we fail, we'll face a magical rupture that could change the world forever.
