There are a lot of popular science books out there that are for everyone. Books that will help you understand the world a bit better without too much effort. Then there are the books that don't take it so easy on you.
For our first SciShow Finds book, we wanted to go with one of the latter. What is Life is understandable to the layperson, but if you don't have a background in chemistry, don't be surprised if you need to re-read paragraphs a few times. But the reward is astounding. Laid out in these pages is a clearly true, clearly understandable argument that life (and evolution) are inevitable chemical processes.
In 100 years, I think "dynamic kinetic stability" (or whatever we end up calling it) will be regarded as nearly as important an idea as evolution from natural selection.
Each of these books (there are only 18 of them) is inscribed with a note of thanks from me. We literally bought every copy the publisher had left.
