From a relaxation standpoint, it was as well.
First book finished was The Seven Wonders, a prequel to the Gordianus the Finder series of novels by Steven Saylor. This book was structured as a series of vignettes, small mysteries that young Gordianus solves while he and his teacher, Antipater the Poet, travel to the Seven Wonders of the Ancient World. Nicely done.
Next was Osprey New Vanguard #41: Confederate Ironclad 1861 – 65, which dealt with the new technology of warships in the Civil War from the Southern side. Mildly interesting.
I followed that with Ready for a Brand New Beat: How “Dancing in the Street” Became the Anthem for a Changing America by Mark Kurlansky. I've enjoyed many of Kurlansky's books, including Salt; this one deals with the growth of Motown in the world of racial separated music; the civil rights movement; the making of the original recording of "Dancing in the Street", and its subsequent covers. I really like how Kurlansky carves out a small piece of history and shows how it affected the world at the time. Very good read, especially for anyone with an interest in the history of the United States in the 60s, or having an interest in music history.
Finally, there was Osprey New Vanguard #56: Union Ironclad 1861 – 65, taking up the topic from the northern viewpoint as discussed in the second book above. Honestly, I didn't get all that much more enjoyment ouf of this book than I did the Confederate one.
