First one was Osprey New Vanguard #190: British Heavy Cruisers 1939 45. Once upon a time, the British fleet was a key component in their Empire. Warships of this a lighter classes were vital. Lots of technical detail in this book, as well as photos and illustrations.
Then, I read Osprey Command #23: Pompey, a biographical sketch of an important general and political figure in Rome.
Most recently, I finished reading The Doctor and the Rough Rider, the first book I've read this month. This is by Mike Resnick, and it's the third book of his Weird West series of novels; sort of steampunk meets Wild West by way of Indian shaman magic. In this one, Doc Holliday meets Theodore Roosevelt to open up the West for American expansion. This series has been an amusing read; reminds me of his Widowmaker series in some ways.
