Weinberg's writings are great. You can find most (all?) of his books here: https://leanpub.com/u/jerryweinberg. I haven't read Becoming a Technical Leader yet, but I have read The Psychology of Computer Programming (among other books of his) and I'd recommend it as well for someone wanting to lead a team.
For me, one of the most valuable things about 'Becoming a Technical Leader' are the exercises/questions at the end of each chapter.
For example, from the end of Chapter 1, 'What is Leadership, Anyway?': "Make a list of situations in which your presence seems to increase the productivity of others. Alongside this list, identify situations where your presence seems to decrease productivity. [...] What do these lists tell you about yourself and the environments that empower you?"
Weinberg has a way of getting you to reflect that I find profoundly valuable, if I am willing to do the work.
