Slater Shrieve’s Reviews > Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime > Status Update

This is a beast of a popular mechanics books. I'd even say it's the clearest explanation of a single interpretation of quantum mechanics, better than QBism by Hans Christian von Baeyer. That's not to say I prefer this interpretation (that's a discussion for another time), but as far as argument clarity goes, Carroll's won.

Ananthaswamy's treatment of the measurement problem is also top-notch and highly recommended.
