The best of what's available at the moment is (IMHO): David Z. Albert, "Quantum Mechanics and Experience" Tim Maudlin, "Philosophy of Science: Quantum Mechanics" (Space and Time is also a good read.) But I'm actually contemplating writing a book of my own because I think there's still a pretty significant gap insofar as none of these books get into quantum information theory at all, which I think is crucial to having a really solid understanding. Another really good book is this one: https://www.amazon.com/Quantum-Challenge-Foundations-Mechanics-Astronomy/dp/076372470X/ https://www.amazon.com/Quantum-Challenge-Foundations-Mechani... though it's a tad pricey, but it's actually a really good mix of technical and historical content because it describes the experiments that were done to show that the many unintuitive predictions of QM are actually true.
