A Stroke of Midnight — Laurell K. Hamilton

How much of my human side will I have to give up, and how much of the sinister side of faerie will I have to embrace? To sit on a throne that has ruled through bloodshed for centuries, I might have to become that which I dread the most.

In Los Angeles she is Meredith Gentry, private investigator. In the faraway world of faerie she is Princess Meredith, heir to a dark throne. In this realm of peril and deception, adversaries watch her every move, while the enemies of her aunt, the queen, lay in wait to usurp power. For the first time in history, human police will enter faerie--and Meredith will need all her allies when fate leads her into the arms of Mistral, Master of Storms, the queen's new captain of the guard. Their passion will awaken powers long forgotten among the warriors of the court--and as Meredith's enemies gather, both courts of faerie will face dire threat.
