Stephen Hawking is fun to read about, he's an interesting fellow.
Though this book is brief on science, it does a good job at covering the broad range of his work.
Don't expect to get a deep understanding of the physics.
For that, read:The Black Hole WarBlack Holes and Time WarpsBlack Holes and Baby UniversesThe Grand Design
I have to rant about one thing:
Kitty Ferguson repeats a sickening myth that the Fukushima Nuclear Disaster was "deadly".
The TSUNAMI was deadly, killing tens of thousands!
The reactor meltdown was NOT deadly, only 2 workers taken to hospital with radiation burns.
You cannot call that deadly in the shadow of death caused by the Tsunami.
