Schooling the Duke — Christi Caldwell

A lady betrayed... Finishing school instructor, Mrs. Rowena Bryant is hated by her students, revered by the headmistress, and absolutely determined to maintain her financial security. Deceived years ago by the only man she'd ever given her heart to, Rowena relies on no one but herself -- that is the best way to keep her most scandalous secret. A soldier turned duke... When Graham Linford returned from war on the cusp of death, he discovered he'd been betrayed by the woman he loved. From that moment, Graham shaped himself into an unfeeling nobleman, refusing to ever suffer the agony of betrayal again. Now a duke, Graham is determined no one will ever discover the touch of madness that has haunted him since battle. Lovers reunited... When Graham finds himself named guardian to a young lady, the woman sent as a companion to his ward is none other than Rowena Bryant. With every moment spent together, their passion reignites, and the walls they've built to keep one another out begin to crumble. But when their dark past tests them again will true love be enough to repair their damaged hearts?
