If I had a reader I'd tell you all what ebook I am currently reading. Since I don't, I can't.
However I can tell you what paper book I'm reading. "Dreadnought" by Robert K Massie. Details the background to World War 1, especially the naval rivalry between Britain and Germany from 1890 to 1914.
Fascinating, excellent. Full of amazing, real-life characters, brilliantly portrayed. Highly recommended.
