First was Osprey Fortress #88: The Mannerheim Line 1920 - 39 which talks about the fortifications that helped hold the Russians somewhat at bay during the Winter War. Somewhat interesting.
Second was The Dark Side of Disney which is about various naughtiness that the author has done in and around Disney World. Nothing is condoned, but much is described, such as ways to limit your spending at the parks. Having been to some of the places described, I found it amusing, but not all that helpful, at least to me.
Finally, there was Osprey New Vanguard # 29: German Armoured Cars and Reconnaissance Half-Tracks 1939 - 45 which I didn't find as interesting as I'd hoped. The photography was not the best, and the plates weren't as good as some other Osprey books have been.
