The go programming language book. Not focused on web development whatever that means particularly but introduces a lot and some advanced concepts and constructs of the language that are very useful/fundamental in server programming. I think GOPL is the only book you need to read about golang. I did not read other related books though so take that last statement with a pinch of salt.
