A strange mixture
This is a strange mixture of advanced physics concepts and personal confession. The author is clearly mesmerized by Stephen Hawking and appears to suffer from an inferiority complex combined with hero worship. Even though Susskind does his best to explain black hole physics simply, with little mathematics, some of it is comprehensible and some is just not, at least to a lay reader with a strong interest in science (e.g. me). I could not follow how string theory has been derived or why we need it, coupled with the fact that he freely admits that experiments which can confirm it may take years if ever to develop. An interesting book but needs reworking, I think, unless you have a strong basis in modern theoretical physics. On the other hand if you enjoy psychology, Susskind's self-portrait, with his conflicts and barely-suppressed neuroses not to mention what look like stomach-cramping efforts to contain his egomania, is rather compelling.
