Books for Gifted adults are rare, so when the question of giftedness it is almost always that of children. This book is not explaining the discomfort of gifted adults, it also provides the root causes as well as their intrinsic operating mode. It also broadens the debate well beyond IQ points. And that I had not seen anywhere else. To such an extent that certain passages may frighten because this book also highlights the dangers of giftedness neurologically and on the psyche. But thanks to him I finally know that I am not guilty of feel things more strongly than average although this may unfortunately generate hostility from non-gifted. I do not know if they would struggle to read it easily as explained in another post. But now I know that I expect out of a book that would tell me how the non-gifted because the gap is even more accentuated than I thought and it is far from the only concern IQ, then we need that we also explains their difference. Gifted or those who believe to be, if you have questions on your inner nature this is the book for you, but beware: you do not come away unscathed.
