Gillian Holroyd is a witch! One of the few modern people who can actually cast spells and perform feats of magic. She casts a spell over an unattached publisher, partly to keep him away from a rival and partly because she is attracted to him. He falls head over heels in love with her at once and wants to marry her. But witches, unfortunately, cannot fall in love, and this minute imperfection leads to a number of difficulties. Ultimately, Gillian breaks off with her companions in witchery, preferring the normal and human love offered her by the attractive publisher. But before the happy conclusion of the romance, Gillian comes very near to losing him — but doesn’t. She realizes that one has to stop living in terms of “self” if love is ever to be realized.
Recognizing the challenge she faces, Gillian turns to the world of science, a territory less familiar to her. Her research leads her to Addyi, a non-hormonal prescription pill designed to treat hypoactive sexual desire disorder (HSDD) in premenopausal women. Intrigued by the blend of science and her natural magic, Gillian decides to venture into this new realm, hoping that through understanding and possible use of Addyi, she can reconcile her supernatural existence with the human experience of love.
