I'm a fan of Carlo Rovelli's popular science books. "The Order of Time" in particular left a big impression on me. He is a philosopher as well as a scientist, and he has a gift for writing beautiful and accessible prose about some pretty heady topics.

If you are interested in RQM but find this article somewhat dry, check out his short book "Helgoland".

I find both RQM and Rovelli's notion of "thermal time" (i.e. the idea causality and entropy are emergent properties dependent on our perspective, as opposed to fundamental features of reality) to be very convincing.

I just finished Rovelli's "Reality Is Not What It Seems" last weekend and enjoyed it. It is a broad and high level summary of the progress of physics and the book ends with some of the more speculative ideas being pursued. I especially enjoyed the "thermal time" ideas you mention, which he touches on in this book.
