So some time back, before "The Trouble with Physics", Lee Smolin wrote a book called "Three Roads to Quantum Gravity". Is "Three Roads" any good? And does it go into any detail on how LQG works?

I find LQG a little while back, so I read Smolin's "The Trouble with Physics" because I heard alternatives to string theory were presented in it. "Trouble with Physics" was a very interesting book, but it didn't have much about LQG in it. Would I have maybe more luck with "Three Roads"?

In particular, is there anything Lee Smolin has written analogous to Rovelli's "Quantum Gravity" textbook, in the sense of just laying out Smolin's approach to LQG as he sees it? Or is the thing to do if one is interested in that to just read through Smolin's Arxiv entries...?

Thanks!
