By day, celebrated beauty Helena Nash works as a proper companion to one of London's most disagreeable ladies. By night she acts as an illicit messenger between two separated lovers. Masked and disguised, she falls into the path of a shadowy stalker. Fearing for her safety but unwilling to halt her nocturnal forays, Helena seeks out Ramsey Munro one of three men who pledged years earlier to serve her family in times of need.

Handsome and elusive, the notorious Scotsman is London's most accomplished swordsman and represents everything Helena wants but can't have freedom, adventure, and passion. Now she demands that he teach her his formidable skills, a commission that may prove cool, collected Helena's undoing. For Ramsey has seen through her disguise...and soon vows to teach her both the way of the sword and the deliciously wicked pleasures of the flesh.
