==Book Description==
Abigail's future looks bleak. Although a member of Britain's aristocracy, Abigail has led a sheltered life in her father's country manor house. The news that he has arranged for her to marry Lord Sutton, a titled man known for his profligate behavior, changes everything. Desperate, Abigail arranges to elope in the middle of the night with a neighbor she has dreamed of since childhood. When the plan goes awry and Abigail becomes deathly ill, she is rescued by a kindly stranger - whom she soon learns is Lord Sutton. Tedric is nothing like the rake she has heard is Lord Sutton. Are the rumors false? Or is she truly bound to a man who values nothing about her except her family name?
