It is wonderful for reasons I can't explain to read of our close relationship with a dead planet tens of millions of miles away. For instance, we learn early on in the book that Martian rock, having travelled that fabulous distance, bashes onto the surface of our planet at a rate of about 100 tons annually.
Hancock delivers the right information at a good pace and does not spoil the read with unnecessary eggheadspeak.
It is undeniably riveting to learn that vast pyramidal monuments on the surface of Mars, one estimated at 1/2 mile in height, are situated roughly in relation to the poles as are those similar, but considerably smaller in scale, at Giza. The mind will find it hard to rest after reading about this and many other jaw-dropping observations.
The computer-enchanced photographs are startling. The illustrative diagrams are easy to absorb.
It matters that the book is read widely. It will change fundamental notions for the reader about what is means to be human on this planet.
