Book three of the World of Sin series Ryan Stonebridge and his friend Kristian Hurst have travelled to London and Paris on their “gap year” adventure, before starting university. Now it’s on to Rome. The American girls they met in Paris are along for the ride, providing lots of sexy fun for the boys. But as no one in the foursome is looking for commitment, there’s still plenty of scope for hooking up with the locals. Voyeurism, cougars, risky outdoor sex and threesomes abound in the Italian leg of the boys’ European adventure.
