Anne Bishop is one of my all time favorite authors. If you haven't read her "Black Jewels" series then now is a great time to start. "The Invisible Ring" is part of the Black Jewels collection, though it is a stand alone book that is separate from her Black Jewels trilogy. It is also an old favorite of mine that has been re-released recently and that gives me the opportunity to share it with you.
From the back of the book:
Jared is a Red-Jeweled Warlord bound as a pleasure slave by the Ring of Obedience. After suffering nine years of torment as a slave, he murdered his owner and escaped--only to be caught and sold into slavery once again.
Purchased by a notorious queen, Jared fears he will share the mysterious fate of her other slaves--never to be seen again--and so prepares himself for death. But the Gray Lady may not be what she seems, and Jared soon faces a difficult decision: his freedom..or his honor.
