If you are looking to learn about the history of Scrum and the reason behind why the practices and approaches work, check out Scrum: The Art of Doing Twice the Work in Half the Time by Jeff Sutherland and J.J. Sutherland.
I got a chance to be a part of a rather small event where Jeff discussed this book. He shared many of the stories from this book, and he talked about the impacts he has seen on all types of organizations including schools, hospitals, and research institutes that leverage Scrum to manage delivering day-to-day.
I definitely recommend giving this a read — all leaders working with Scrum teams should give this book a read.
