The Greatest Danger Is to Love...
An innocent at thirty, Brett Benton had never known desire until she met Alex Sanborn. His bold gaze stoked a hungry yearning within her, but her pride rebelled at yielding to the man who suspected she was a British spy.
A fierce patriot, Alex had to protect his shipping business from the enemy's grasp. And Brett was a seductive mix of beauty and spirit, tempting him with paradise...
Amid the fires of war and treachery, their hearts were the battleground... and love, the elusive prize.
