A Crown for a Lady by Tanya Anne Crosby

A deception of royal proportionsthrust Ian MacEwen into the very center of the ton’s marriage mart, forcing him to choose a bride who would be queen. All he wanted was to uncover the answers denied him from birth. Instead, he found saucy Claire Wentworth, a fearless woman with grass-green eyes who needs his protection—and his love—whether she knows it or not.
Fallen from grace, danger stalks Claire Wentworth at every turn. She needs a champion, but what she gets instead is a royal mystery. The man all of London hails as “Prince” instead strikes her as a rogue adventurer—who no doubt rouses her slumbering heart to wide-awake desire.
