@franktaber@mas.to IMO the best start is the book Peopleware. Pragmatic through and through. The text is approachable without dumbing down. Gives a surprisingly thorough overview of good management practices in software.
I also enjoyed Resilient Management by Lara Hogan. Again, super pragmatic.
I need to do a bit of catching up to do on the management books that have come out in the past four or five years as it looks like there have been a few good ones, but those two are great starts.
