I decided to read this series, because I had started the Anita Blake series by the same author. This book starts off introducing us to Merry Gentry, a fairy princess living under an assumed name and working for a detective agency. She takes a case in which she goes undercover, but is discovered. She is taken to see King Sholto, King of the Sluagh, who proposes an alliance with her against her insane aunt. Her aunt is the Queen of Air and Darkness. She wishes to continue the bloodline of the throne and tells Merry whoever produces an heir first shall inherit the throne. Merry must race her cousin Cel to produce an heir. I am not really crazy about erotica books, but this one was very interesting and I hope the rest of the series is good.
