I just finished Einstein Must Die! by Chris Kohout. Really well done, I enjoyed it a lot. It starts in 1910 and has the classic Tesla vs. Edison rivalry. You can read the synopsis and my full review on Goodreads at the link below; I had spoilers that I had to remove for this post. I suggest it for anyone who likes alternate history (reminded me a lot of some Turtledove stuff) or steampunk/dieselpunk.
Disclaimer: I won this book in a Goodreads giveaway contest. I was very impressed with this first novel in the new Fate of Nations series. I would consider it part alternate history and part dieselpunk (a bit more advanced technology than steampunk). I liked the characterization, several of the main characters were developed quite nicely. The first part of the book about Tesla really set the stage for him and created some empathy in me for the character.
The mix of different levels of technology was interesting although I had to consciously suspend my disbelief for one particular invention. The Tesla vs. Edison rivalry is in full force here and causes some very interesting plot twists. It’s always interesting to see how politics can influence science and this was a perfect example of that.
I am very much looking forward to the next volume in the series, this one ended with a nice lead-in for whatever happens next.
