Bathsheba : a novel / Jill Eileen Smith.

Enhanced descriptions from Syndetics:

Bathsheba is a woman who longs for love. With her devout husband away fighting the king's wars for many months at a time, discontent and loneliness dog her steps--and make it frighteningly easy to succumb to King David's charm and attention. Though she immediately regrets her involvement with the powerful king, the pieces are set in motion that will destroy everything she holds dear. Can she find forgiveness at the feet of the Almighty? Or has her sin separated her from God--and David--forever?

With a historian's sharp eye for detail and a novelist's creative spirit, Jill Eileen Smith brings to life the passionate and emotional story of David's most famous--and infamous--wife. Smith uses her gentle hand to draw out the humanity in her characters, allowing readers to see themselves in the three-dimensional lives and minds of people who are often viewed in starkly moralistic terms. You will never read the story of David and Bathsheba in the same way again.
