I loved the book The Billion Dollar Molecule (Reviewed by Nature here: https://www.nature.com/articles/nbt0594-521.pdf) about the founding of Vertex Pharma. Really drives home the amount of money, time and luck it takes to make a breakthrough - the author needed to write an entire second book to get to the part where they started making real revenue. The second book isn't as good, but if you like the first enough you might try it anyway.
