The Darkest Night by Gena Showalter
I just finished re-reading The Darkest Night (2008), the first book in Gena Showalter's fantastic Lords of the Underworld series. For someone who generally doesn't appreciate series books at all--too much commitment, too much impatience with waiting for the next installment, often takes too long to make any progress with the overall plot--I'm a huge fan of Lords of the Underworld. I rarely re-read books, and most of the books from this series are on my permanent rotation list.
Ashlyn Darrow has an ability she can't control; while in a specific location, she can hear every conversation that has ever occurred in that place. Imagine trying to exist on a day-to-day basis while being inundated with unwanted voices.
After hearing about the Lords, she goes to see if they can help her learn to control her ability. While trying to reach them, she's found by Maddox, the Lord inhabited by the demon Violence and cursed with having to die every night at midnight. Ashlyn's voices cease while in Maddox's presence.
But Maddox and the rest of the Lords fear Ashlyn may be Bait sent by the Hunters who want to eliminate them.
If you haven't read the series and enjoy paranormal romance, the first book in the Lords of the Underworld series is a great place to start.
My overall personal rating of The Darkest Night is a B+.
