True, the book does not represent Hawking's latest views, but for those wishing to wade into the shallow end of Hawking's writing this is not bad.
Coming in at a short 112 pages, this heavily illustrated book gives one a opportunity to at least familiarize themselves with issues that Hawking gives much more detailed treatment to in his other works: A brief history of time, Black holes and Baby Universes and On the Shoulders of Giants.
One good for instance is his chapter on the arrow of time. In it Hawking observes that there is not only one but several arrows of time. Though he only talks about cosmic expansion, gravitation and the perceptual arrows of time (and not Kaon decay or the quantum arrow of time which may be the master arrow), one still gets the idea that there are physical reasons for why time assumes a directionality.
Another example is his final chapter on the quest for a theory of everything. Though now -- particularly with waning enthusiasm for string theory -- there is reasoned speculation that maybe there may never be a theory of everything, his chapter stills reflects how many view still view the search.
And finally, his chapter on black hole radiation harkens back to the research that originally put him on the map, his 1974 finding that black holes do indeed radiate and even given enough time will decay.
All together, Hawking's book shows the lucid explanatory power of one who both knows and knows how to explain.
So yes, by all means, read this book, but don't stop here and read the rest of his books too.
