Top book (this will seem like a strange one) but it was 'Range178' by David Epstein. A book about "how generalists triumph in a specialized world" an amazing book it really taught me why generalists make better Product Managers136 and where my role as a PM really sits on a team.
Which is not to be an expert but rather to have a broad range of skills/understanding across the many facets of product (from tech to marketing to user science, etc) to leverage this knowledge in order to solve wicked problems - or at least ask the right questions of the experts around me in order to best solve the problem.
