I am still on my quest to real every Newberry Award winning novel written since I was born. I haven't been reviewing all the books because honestly some of them haven't been all that noteworthy.
I just finished Lincoln: A Photobiography. I will say I'm a little perplexed as to why it won. It's a great historical account of Lincoln's life, but I'm not sure the book holds much appeal for most kids. I also think the average upper elementary or middle school student would need to read this as part of a unit on Lincoln or the Civil War. It's a heavy read and would be very difficult without lots of background building and support.
That said, I really enjoyed it. It's a dry read, but I think it does a good job of painting the picture of Lincoln's life. It helped me have a clearer understanding of the Civil War. My students weren't rushing to library to check it out after me. But I read it while we were doing a unit on Harriet Tubman. It helped me give them a clearer picture of the era and they were interested to read excerpts and look at the photographs.
So this isn't one with huge mass appeal. But if you're a history buff it's well worth checking out.
