I don't know why DK discontinued their biography series, but as far as I know they did, after a pretty short run. This title was superb and I suspect others in the series were as well. Maybe they will bring it back with Common Core? One can hope.
I've read other biographies of Eleanor Roosevelt but for a short juvenile book, this covered her life incredibly well! I wondered if it would cover the affair of Roosevelt and Lucy Mercer. Not only did it mention the original affair, it informed readers that she was present when he died AND when Eleanor got down there to her husband! That seems just plain cruel to let Mrs. Roosevelt know his interest in his mistress continued all these years! As usual, the remarkable woman overcame that blow and went on to continue her life of service to Americans and the world.
The photos, unsurprisingly, were superb and show that actually Eleanor was a very attractive lady. Normally one only sees photos when she was elderly which does her a real disservice. In addition, the text was also well written with excellent side articles explaining events that touched on Eleanor's life.
If I were handing a kid a biography of Eleanor, I would start with this book, then of course move on to Freedman's biography of her. Highly recommended for adults, not only kids.
