Saw the title I thought finally a book that will tell us about those children who are not necessarily "extraordinary" in the sense of early shot with 3 years in advance, bespectacled, the nerd of the class ...
not really found that ...
(Coverage once again falls into the cliché and it's a pity ... I guess those who choose the image do to hook the reader but in this case, why put a baby who does math?)
