My name is Michael Donovan. I'm a halo hunter. And I want to believe. For ten years I've been collecting halos, lost when fallen angels purposefully left heaven to mate with human women. But in all that time, I've never seen an angel. In Paris searching for halo number eighteen, I get a lucky break when a gorgeous woman named Vinny offers up the halo's location—for a price. Even though she sends up all kinds of warning signals, I can't resist her offer. She's too interesting, too mysterious...and way too sexy. Sure enough, soon I'm being shot at, followed by strange men, and learning more about the supernatural world from Vinny than I ever could have imagined. Why are the pretty ones always so dangerous?
