Everything was perfect. Louis Tomlinson had a successful career, a loving family, four best mates and - best of all - his lovely girlfriend, Macy. But in a sudden turn of events, Macy dumps him with no warning three days before he proposes to her. And in an even more twisted turn of events, she goes missing, leaving him broken and confused. Now it's up to him and the boys to live up to their Adventurous Adventures of One Direction status - and find out where Macy really is. All during the biggest tour of their lives.
