Surrender to the Highlander by Terri Brisbin

Torn between honor and desire

Innocent Margriet Gunnarsdottir carried a heavy secret. She faced a perilous journey to the wild and distant north of Scotland, and her safety lay in her adopted disguise—a nun’s habit! But her only protector, a proud, rough-hewn Highlander, made her ache to share her crushing burden.
Rurik Erengislsson had sworn to see her home and unharmed. A woman promised to the service of God should be shielded and honored—not desired! Yet Rurik was tempted beyond reason to make this beautiful waif his own.
