Brazen

If he could, Captain Gavin Briggs would forget his years as an assassin in England's war against France. He's seen enough death and suffering to last a lifetime, and now all he wants is some peace. But that peace comes with a heavy price tag, and as the second son of a penniless Viscount, Gavin may just have to take on one last mission: locate an estranged granddaughter for a dying duke, a peer with the deepest of pockets ... even if it means risking what's left of his soul.
Christina, Lady Fairhaven, always knew her loving parents had adopted her when she was very young, but she has never imagined any other family. So when a letter arrives accusing her troublesome brother of the worst of deeds, she will not rest until she sees her brother safe and the blackmailer in chains. But when Gavin arrives telling her of her true heritage, Christina engages in a bit of blackmail of her own: she'll return with him to her grandfather if only he'll first help take on the blackguard threatening her family. With peace nearly in his grasp, Gavin agrees--but as they get ever closer to their quarry, a spark of attraction grows into something so much more ... and Christina and Gavin realise that happiness may come at a greater cost then they'd ever imagined.
