For the person on your list who has everything:
This book takes a dramatically original approach to the history of humanity, using objects which pervious civilizations have left behind, often accidentally, as prisms through which we can explore past worlds and the lives of themen and women who lived in them. The book's range is enormous: it begins with a chopping tool from Africa (one of the earliest surviving objects made from human hands) to a solar powered lamp and charger made in modern-day China. MacGregor (who is the director of the British Museum) shows how these objects were and still are significant. This is on of the most engrossing and unusual history books published in years.
For the history buff on your list:Award-winning author Tim Cook turns his narrative powers to the conflict between two towering Great War figures: Sir Arthur Currie, Canadian Corps commander and a brilliant, morally brave general and innovator who overcame many of the challenges of trench warfare, and Sir Sam Hughes, Canada’s war minister who accused Currie of being a butcher, a callous murderer of his own men. Set against the backdrop of Europe’s battlefields and Canada’s political tumult, The Madman and the Butcher is a powerful double biography that explores the nation’s discomfort with heroes, the need to place blame, and the very public war of reputations that raged on after the guns fell silent. Using newly uncovered sources, Cook creates a haunting portrait of our greatest battlefield general and the man who tried to destroy him.
