Seduced by Moonlight — Laurell K. Hamilton

"I am Meredith Gentry, P.I., and Princess Merry, heir to the throne of Fairie. Now there are those among my guards who whisper I am more."

The queen's mission to get Meredith pregnant and beat her cousin Cel to the crown is taking longer than expected. Even though Meredith spends each night with the queen's immortal guards, no child has come of their decadent pleasures. But something else is happening. Enemies are growing in number every day. Meredith's magic surges through her like never before, transforming her in wild and unpredictable ways. And Meredith is just beginning to learn what incredible power she possesses. . . .
