Readying herself to compete for the prestigious Rosewood Prize for Mathematics, Letitia Fenley is suddenly asked to take on another responsibility - managing a secret haven for England's women scientists. Having spent the last six years on her own, Letty doesn't want the offers of friendship from other club members and most certainly doesn't need help from the insufferably attractive Lord Greycliff. Lord William Hughes, the Viscount Greycliff cannot afford to make any mistakes. His lifelong dream of becoming the director of a powerful clandestine agency is within his grasp. Tasked with helping Letty safeguard the retreat, Grey is positive that he can control the antics of the various scientists as well as manage the tiny mathematician - despite their historic animosity and simmering tension. As Grey and Letty are forced to work together, their mutual dislike turns to admiration and eventually to something... magnetic.
