Riley Stone is the handsome brother, the charming one. Everyone who meets him compares him to his father, which in his mind is not a compliment. But he's never met a woman he couldn't charm, until he meets Di, an acerbic, smart-mouthed, passionate activist who has no time for him or his charm. On the run, in the midst of danger, the blistering passion they share explodes. Can these two opposites find common ground, or will Di smash Riley's stone heart?
