Rory McIlroy contains multitudes. He can overwhelm a golf course with his transcendent talent and then, at the next tournament, look utterly lost. McIlroy is golf’s most eloquent ambassador and a trash-talking troll, sometimes in the same press conference. The child of a working-class family from a small town in a war-torn homeland now commutes to work in his own private jet and counts billionaires as confidants. A dozen years ago, McIlroy asked Alan Shipnuck a question about the player he had modeled himself after, Tiger Woods: “What’s he really like?” As McIlroy enters the last act of his highly eventful career, this book is a chance to redirect that old question and try to understand a man of deep complexity and contradictions.
