Reality is Not What it Seems: The Journey to Quantum Gravity
by Carlo Rovelli
I wish he had spent much more time on the LQG explanations than he did. What he did explain struck me as being a very mathematical way of looking at reality - not in the sense of equations, but a style of description or thinking. And from that point of view, I liked the definition of the basic constituent of spacetime and of the evolution of time - essentially a graph whose components can interact, and whose very interactions create the phenomenon of time passing. But given that I could describe its essence so compactly, I suspect there's more to it which would have been explainable in a non-jargony way with a little more space - but maybe I'm wrong and that's really it.
