Next, if you (as developers naturally do) struggle with the idea of management, structure and order, read "The E-Myth Revisited".
Peopleware TL;DR: Good teams are united by a strongly defined purpose (eg. get X defined and tests written by date X), and that is almost NEVER the same as the goals of the business (which is to make money). Don't create internal competition; overtime kills productivity; physical/mental space allows creativity; interruptions are deadly.
The E-Myth TL;DR: Aimed at small business owners, but as a team lead you're effectively running a business, and the rest of the company is your customer. It's a mere 5 hour read... JFDI :)
And if you're feeling really bookish, "The Mythical Man Month" - if you're under 50 this will shock you, because you'll realise that software in 1970 had the exact same problems that we do in 2015.
