Let me preface this by saying that I have a better command of chemistry than the average person. I don't consider myself a great chemist, but with my current job, you could make a case for my career being chemistry.  With that said, I think this is a very fun-factable book in the way that when you read it, the stories are so interesting that you immediately want to go tell someone about the weird little thing you just learned. Overall I think the science is pretty accessible, but towards the end, it got a bit too heavy even for someone working in STEM (partially because I do not like reading about too heavy science in my free time since it feels like work).  I think if you consider yourself a science person in any way, this book will be more of a light read for you, but someone without a science background may find it slightly more challenging not to be overwhelmed. I truly think it's easily accessible to those who passed high school chemistry.
