A Most Dangerous Profession (The Hurst Amulet, Band 3)

New York Times bestselling author Karen Hawkins presents the third book in her sparkling Scottish Regency Hurst Amulet series, featuring undercover operative Robert Hurst.
Robert Hurst, a secret operative in the King's service, is tracking down the mysterious onyx box needed to ransom his kidnapped brother. Moira Muir is seeking the same box for a very similar reason: her young daughter is being held captive. But there are further complications: years ago, Moira and Robert had an affair before he learned she was a counter-spy. And when she discovered she was pregnant, she tricked him into marrying her. Now the two must put aside their anger and join forces to find the box and rescue their daughter...finding love all over again along the way.
