Those times when people composed beautiful fairy tales and eerie legends about magical people are long gone, but fairies still live among us, hiding under the illusion of human appearance. October Day was unlucky enough to be born a half-breed changeling, alien to humans and unwanted by fairies. But on the other hand, she masters what the immortals have not been willing to learn over thousands of years: the ability to use the experience and skills of people. This leads her into knightly service with Sylvester Torquil, Duke of the Shadow Hills. However, after Oktober finds herself at the center of the intrigue of an infinitely more powerful than herself, Simon Torquil, the twin brother of her lord, and finds herself imprisoned for fourteen years in the body of a fish, she acquires not only a persistent dislike for water, but also a categorical reluctance dealing with the magical world in general. Her former love, Connor O'Dell, entered into a political marriage with Raiselin Torquil, Sylvester's heir, and her mortal husband Oktober and the daughter born from his marriage became strangers after fourteen years of absence. Oktober lives alone, apart from the company of a couple of cats, and works as a private detective in the human world.
