Opinions on Rovelli's General Relativity: The Essentials?

[The Bill]

I recently noticed that "General Relativity: The Essentials" by Carlo Rovelli has been published. Based on the description, table of contents, and the Amazon reviews, it seems to me that it might be a spiritual successor to Dirac's "General Theory of Relativity." Is that an accurate assessment?

If you've had a chance to give it a look, what were your thoughts? What purpose(s) do you think this text would be good for?

The book discusses some basic GR aspects of GPS, which can hardly be found in other books.

It looks very different from Dirac's book to call it a successor in any sense. Dirac has no philosophical discusstions at all, Rovelli on the other hand has plenty.
