Ask HN: What books can teach me engineering management skills?

I was recently promoted to an engineering management position of a tiny team. I'll be expected to contribute code while we're still small, then gradually fill my hours with more managerial activities as we grow.

I've never managed people, let alone an engineering org. What books can teach me solid principles for maximizing our team's impact? I've read so many horror stories about "We switched to X software development philosophy and it was a disaster: News at 11" I'm wondering if there are classic instructional books/resources that still ring true today, cutting through the latest fads.

Is the Mythical Man Month still a good start for the software/project side of things, for example?
