I'd say that most of the value from an MBA program is through your peers rather than from books. To complement the reading, I would recommend reaching out to other entrepreneurs.

They don't read books at HBS. Instead students go through about 600 cases over the course of two years. The cases are interesting but the bulk of the learning comes from how the professors dissect the case and facilitate the classroom in debating the various positions. Of course you could order all the cases from HBS but that's pretty pricey and you won't get the teaching notes.
