I thought it was really thorough and quite technical, so if you're interested in the early day of electricity more than just personal anecdotes, then this book might be for you :)
Unfortunately most of my books are in storage at the moment and I can't get the exact details for you. But I do have a book on Tesla's inventions and patents. I found that very interesting. The diagrams and descriptions are very informative. I think the book is: https://www.amazon.com/Complete-Patents-Nikola-Tesla/dp/1566...
Best is to experience it in person at Nikola Tesla museum in Belgrade, Serbia. It keeps his remains and many documents and ideas and attracts like-minded fans from around the world.
I’ll put in a vote for Wizard: the life and times of Nikola Tesla. I knew very little other than “Tesla == weird genius”, and the book gave me a much deeper view of his work, from trying to run power through the ground to building drone boats.
