Divine Misdemeanors - Laurell K. Hamilton

You may know me best as Meredith Nic Essus, princess of faerie. Or perhaps as Merry Gentry, Los Angeles private eye. To protect my unborn children, I have turned my back on the crown, choosing exile in the human world with my beloved Frost and Darkness. Yet I cannot abandon my people. Someone is killing the fey, which has left the LAPD baffled and my guardsmen and me deeply disturbed. I thought I'd left the blood and politics behind in my own turbulent realm. But now I realize that evil knows no borders, and that nobody lives forever-even if they're magical.
