Lady Juliet is happy. Very happy. After all, she’s engaged. Perhaps it is slightly odd that she rarely sees her betrothed. She also wonders why various men give her sympathetic glances when she mentions her future husband, the Duke of Sherwood. When she learns the Duke of Sherwood is spending time with another woman, there’s only one thing she can do: discover the truth herself.

Lucas, the Duke of Ainsworth, enjoys science and the calm normally found in laboraties. When he travels to the Lake District he is shocked to discover Lady Juliet in disguise. Lucas vows to help her, no matter how distracting her alluring presence is.
