The Taming of Annabelle (The Six Sisters #2)

Miss Annabelle Armitage was pea-green with envy. What a cruel world it was when her spinster of an older sister could enchant the dashing Lord Sylvester Comfrey! Annabelle’s own passionate nature was surely better suited for such a one as Sylvester.
 
Alas for Annabelle, Comfrey seemed to care for her not a jot. Determined to get a bit of her own back, even if it meant marrying another, Annabelle found Peter, Marquess of Brabington, a most attentive admirer.
 
War hero though he might be, Peter was ill-prepared for his coming fight for Annabel’s true love—and a battle it would be, winner take all . . .
