In the seaside village of Kinlough, on Ireland’s west coast, three old friends meet for the first time in years. They were part of an original group of six inseparable teenagers in the summer of 2003, with motherless, reckless Kala Lanann at its white-hot center. But later that year, Kala disappeared without a trace. Now remains have been discovered in the woods, including a skull with a Polaroid photo tucked inside.
