The Obsession — Jaid Black

Neil Macalister, a conservative and oh-so-proper lecturer of mathematics at the University of Edinburgh, thought he was happy with his sensible, ordinary life. But from the moment he laid eyes on Valentina Jason-Elliot, a sexually liberated woman ten years his junior, he became obsessed with having her.

Neil quickly discovers there aren't any lengths he won't go to in order to capture the object of his desire, for he's determined to have Valentina bound to him...in the heart and in the flesh.
