Danielle Steel 
The Mistress 

Natasha Leonova’s beauty saved her life. Discovered on a freezing Moscow street by a Russian billionaire, she has lived for seven years under his protection. Believing his generosity will always keep her safe, Natasha is careful not to dwell on Vladimir’s ruthlessness or the deadly circles he moves in.
Until she meets Theo Luca. The son of a famous and difficult artist, Theo and his mother own a restaurant filled with his late father’s artwork. There, on a warm June evening, Theo first encounters Natasha, the most beautiful woman he has ever seen. And there, Vladimir lays eyes on Luca’s artwork. Two dangerous obsessions begin.
Theo, a gifted artist in his own right, finds himself feverishly painting Natasha’s image for weeks after their first meeting. Vladimir, enraged that the paintings are not for sale, is determined to secure one at any price. And Natasha, who knows that she cannot afford to make even one false move, nevertheless begins to think of the freedom she can never have as Vladimir’s mistress . . .
