Sheik's Rule (Desert Justice [Intrigue], 1)

He's an investigator on a mission, but it's impossible to ignore the brilliant woman helping him complete it… His sister's life is at stake, and despite his wealth and power, Sheik Emir Al-Nassar feels helpless. At least heading his family's security agency provides him with resources to track down her kidnappers. But when the ace profiler he's sent turns out to be K. J.—Kate—Gelinsky, Emir is furious. Finding the kidnappers' desert hideout is dangerous enough without the distraction of a beautiful woman. But K.J. is unlike any woman he's ever known. Her fearlessness and incisive mind inspires Emir's admiration. And her compassion breaches his guarded heart. Still, rescuing his sister is a perilous mission. And allowing desire to cloud his focus could endanger them all. Desert Justice
