Is there a cure for longing? Escaping heartbreak, a raw and humble Eugene Mahon leaves small town Ireland for London. His horizons expand as he meets and befriends men from all over the world on the Shoreditch building site where he works. The good times roll, but the shadows of the past loom over him as he lodges in the pub his late father Seamus lived in when he worked in the city years before. The pub is run by the same landlady, Della, and her daughter Julia, and Eugene's appearance bring Della's own memories of his father flooding to the surface, revealing secrets that she'd hoped to keep hidden forever. Eugene's initiation into the brotherhood of the building site is shattered when he wakes one morning in a police cell, beaten and bruised, with no memory of how or why he got there. In the midst of accusation and hostility, Eugene must uncover truths that will change his life, and the lives of those around him forever.
