THE UNDERCOVER BILLIONAIRE is the third in the saga of the three Tate Brothers by Jackie Ashenden. Alpha, handsome, and sexy brothers Van, Lucas, and Wolf are all SEALs. This is Wolf's story. He is home on bereavement leave due to the death of his adopted father, Noah Tate. A letter from his departed father orders him to finish a mission. A mission that started many years ago when Wolf infiltrated the De Santis family and served as a double agent for his father in a feud that started when the best friends argued over oil land holdings. It became a long lasting feud and in his letter to his son, his last request was for Wolf to kill Cesare de Santis.

Wolf sneaked into the De Santis mansion, escaped detection from the large security staff guarding the palatial home and his daughter, Olivia. He sneaked into her bedroom and watched her sleep. They were childhood friends, but he had not seen her for ten years as he completed training, then missions in the SEALs. She was beautiful at 28 years old and had kept in touch with Wolf during that time by e-mails. They were childhood friends and now he needed Olivia. She kept her father's schedules and private files. Unknown to Olivia, her father was heavily involved in illegal arms deals and used his daughter as he used everyone in his shady life. Olivia only wanted her father's love and would do anything he asked her to do. She has no clue what a dirty, dishonest man her father is. Nor is she aware he would give her away to his business partner, an older man, Daniel May. She could barely tolerate him, she has no feelings for him. Her father would never force her, would he?

When Olivia awakens and sees Wolf, she smiles. When he tells he he is there to kidnap her, she goes willingly. She has been in love with him since she was 15 years old. He takes her to a five star hotel and begins to tell her about her father and how his mission is to kill him. How shameful what lengths a parent would go to and what their unsuspecting children would do for their gain. Olivia refused to believe Wolf and got him drunk and he fell asleep and she escaped. When she returned to her father, he was very angry and he told her she will marry Daniel May and she is not to ask any questions about his business or encrypted files. Just obey and don't ask questions. She came to the realization that Wolf was telling her the truth.

Again she is stolen away by Wolf. This time to his boat in the harbor. Slowly, but surely Wolf convinces Olivia that her father is not the man she thinks he is and she is convinced that he does not love her and, in fact, only using her. Their sexual attraction is HOT! This is a gripping adventure that you will be unable to put down. Lies, revenge, sex, surprises, and in the end, love. Ms. Ashenden, what a thrilling story with characters that you will root for and cheer at the finale. I enjoyed it!
