Have I told you about the DK biographies yet? If not, shame on me, because you're missing out if you've not yet heard of them.
I received Joan of Arc's biography for Christmas this past year, and I immediately fell in love with the series. They're short, compact in size and all do, as their titles suggest, contain scads of photographs.
I've burned through my library's scant collection and I found that while they sat in a basket in our living room that houses our library books, Madeleine read them too.
