Professor Albus Dumbledore is said to reveal ” not just his vast knowledge of Wizarding lore, but also more of his personal qualities: his sense of humor, his courage, his pride in his abilities, and his hard-won wisdom.” Of particular interest are the new details we can expect to find regarding “Aberforth Dumbledore, Lucius Malfoy and his family, and Sir Nicholas de Mimsy-Porpington (or “Nearly Headless Nick”), as well as other professors at Hogwarts and the past owners of the Elder Wand. Dumbledore tells us of incidents unique to the Wizarding world, like hilariously troubled theatrical productions at Hogwarts or the dangers of having a “hairy heart.” But he also reveals aspects of the Wizarding world that his Muggle readers might find all too familiar, like censorship, intolerance, and questions about the deepest mysteries in life.”
