I’ve really liked the books I’ve read in Jason Goodwin’s too short Investigator Yashim series, and so I am happy to have his non-fiction Lords of the Horizons: A History of the Ottoman Empire pop up in my eReaderIQ feed as being on sale for $2.99. I’ve read a couple of histories of Constantinople/Byzantium/Constantinople, which pretty much have to have a lot of Ottoman history, but haven’t so far read a book just focusing on the Ottoman Empire itself. And this one got a couple of pretty nice comments from Kirkus and The New York Times Book Review – see the blurb/spoiler.
Lords of the Horizons is $2.99 again right now at Kindle US, but not at Kobo US, at least so far. The links in the OP are still good.
