The Rings that Bind

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
On his terms only 

The day Rosa agreed to wear Nicolai Baranski's ring she wasn't so foolish as to expect love. Yet nothing could have prepared her for the aching loneliness of her husband's constant indifference—an indifference that proved too much to bear. 

Nico is furious—no one turns their back on a Baranski. Rosa has some nerve if she thinks he will just let her walk away. He'll use every sensual trick at his disposal to bring her back, begging for more. And once he's got her where he wants her? He'll let her go. But only when he's ready!
