Based on extensive interviews, access to notebooks, and letters exchanged between the author and Oliver Sacks, And How Are You, Dr. Sacks? reveals a messy, exhausting, insecure and turbulent Sacks - a very different character from the more composed subject of Sacks's own memoir. Where the memoir casts Sacks' life in stone, here we experience the moment-to-moment thrill of his company. The untold story of Dr. Oliver Sacks, his own most singular patient.
