Owner of "the most remarkable mind on the planet," (according to Entertainment Weekly) Daniel Tammet captivated readers and won worldwide critical acclaim with the 2007 New York Times bestselling memoir, Born On A Blue Day, and its vivid depiction of a life with autistic savant syndrome. In his fascinating new book, he writes with characteristic clarity and personal awareness as he sheds light on the mysteries of savants' incredible mental abilities, and our own.

Tammet explains that the differences between savant and non-savant minds have been exaggerated; his astonishing capacities in memory, math and language are neither due to a cerebral supercomputer nor any genetic quirk, but are rather the results of a highly rich and complex associative form of thinking and imagination. Autistic thought, he argues, is an extreme variation of a kind that we all do, from daydreaming to the use of puns and metaphors.
