They once faced each other on a battlefield. Now soldier-turned-spy Jonathan Reese must keep watch over the man he’s never forgotten. A close encounter reveals Karl von Binder, the count’s son, also recalls the day he spared Jonathan’s life. Sparks fly between the former enemies and Jonathan begins to lose perspective on his mission. He knows he must maintain distance because the heat he encounters in Karl’s touch stirs him far too deeply for his own good. He can’t keep away—especially when he suspects someone is trying to kill the nobleman. The spy becomes a protector as Jonathan guards the man he’s begun to care for. Together the men try to puzzle out who would benefit from Karl’s death—and how much they’re willing to trust each other when a torrid sexual fling threatens to become an affair of the heart.
