Disappeared

Julie Welch's sister, Fay, disappears from their hotel in Morocco. Although she leaves a note that she'll be back in two days, Fay doesn't return. Julie's fears intensify when an attack meant for her kills another woman. Julie guesses Fay's destination and rushes to warn her, convinced her sister is in danger. But it's not until Julie reaches Fay—in a prison cell—and learns the reasons for Fay's secrecy that their problems really escalate. Perfect for fans of Tana French and Martin Cruz Smith
