Then a chance encounter opens her heart to a masked stranger…who might not be a stranger after all! Caleb Landis, the army medic behind the disguise, has always admired Kate, even though she only saw him as her best friend's brother. What will it take for Kate to discard her fears and discover the man she's always hoped to unmask?
