"Beautifully evocative and romantic." - NYT bestselling author, Monica McCarty An eighty-mile trek across the rugged, stunning beauty of Scotland’s Isle of Skye isn't something I imagined myself doing. Ever. This isn’t a trail for beginners. And I’m not a hiker. But I have to finish it, even if it kills me. I have no choice. With the ever-changing weather and relentless terrain, I’m in over my head. Rory Sutherland, my guide on this adventure, knows I don’t belong here. We clash with every mile, but we recognize a shared pain. Not only is the journey a struggle, but the tension between us is taut with unsaid words. And hope. He’s broken. I’m damaged. Together, we’re about to make the perfect storm.

The crossing of Ingo is an ancient and dangerous coming-of-age ritual: a journey to the bottom of the world. Sapphy and Conor have been called to take part, the first of human blood ever to make an attempt. But Ervys and his followers are determined to stop them: dead or alive. Helen Dunmore builds her classic, much-loved series up to a breathtaking finale.
