Vanquished by Jo Michaels

An angel fell in love with a vampire. This is what happened next.

Victoria and Vance have been married for centuries, working for God and battling evil at His command. Now, the unusual couple are headed to New Orleans, Louisiana, to investigate why so many humans are losing their souls.
Victoria and Vance are tasked with stopping the thievery, but people aren’t as open to speaking with the couple as they’d hoped. Stakes are too high, and the affected have an unusual power of their own.
It’s a high-stakes gamble as the pair races to find answers before the humans’ souls are lost forever.
