Her Captive Cavalier — Marina Oliver

Determined not to allow a band of roaming Cavaliers to enter her home, Caro threatens their leader with a pistol. When he ignores her challenge she shuts her eyes and fires.

Compelled to nurse him when her shot grazes his head, she gradually realises she must protect him from his enemies.
But that is not enough. His enemies become hers, and to escape them she has to trust herself to his protection.
