It started with a kiss. When nine-year-old Eleanor Abbington first met her uncle's new stepson, Nicolas Norton, the boy rudely stole a kiss from her that set the tone for their contentious and competitive relationship. It wasn't until years later when Nick introduced her to fencing that they finally had a proper outlet for their frequent arguments. Having just emerged from mourning following her mother's death, Eleanor is exactly where she wishes to be at the age of four-and-twenty: an on-the-shelf spinster and unofficial companion to her aunt. Unfortunately, her ambitious uncle has other plans for her future. On the eve of his house party, he lays down his ultimatum: either Eleanor marries the man of his choosing, or he'll force her seventeen-year-old sister to do so instead.
