Benhoff is one of the best in the industry at conveying concepts in a useful way, with devs' personalities and emotions in mind. This book is the best guide that I know of for devs transitioning into lead or senior roles, especially those who aren't sure if they should take the plunge. The most impactful topics are imposter syndrome, delegation, and "defending your team" against upper management. Highly recommended reading for anyone moving into or recently moved into a lead dev role.
