To save her destitute family, spinster Lucy Drake must hide her secret—she can shape–shift in dragon form—and she must agree to the Duke of Greystone's scandalous proposal. She must be the duke's sexual plaything for a fortnight so he will forgive her wayward brother's staggering debts. To find his missing nephew, a half–dragon child stolen by the Drake family three years before, widowed Greystone ruined Lucy's brother at cards, then offered him salvation if he revealed the child's location. But Lucy's brother disappeared before he would give up his family's secret. When Lucy arrives at Greystone's house willing to do anything to save her family, the duke is determined to seduce the knowledge of his nephew's whereabouts from her. But after nights of where he experiences Lucy's fiery passions, Greystone's icy heart begins to melt. When Lucy helps him find his nephew, can a vampire dragon–slayer defy his oath, and give in to love with the woman of his dreams?
