M.J. Rose's erotic thriller THE HALO EFFECT is the first in her series featuring Dr. Morgan Snow of the Butterfield Institute, a sex therapist for a wide range of clients who is drawn into the investigation of twisted murders. It's currently on sale for 99 cents for Kindle. The book trailer is below. If you don't know M.J., she is a true outlier, someone who broke into publishing in the late 1990s by printing and hand-selling her own books back when self-publishing was still the supposed mark of a hack and amateur. Now she's come full circle and putting out her own e-books again.
