Sisters: Venus & Serena Williams by Jeanette Winter is in their signature style of text and illustrations. Sisters is a simple, poetic book about the Williams sisters. There is not a lot of background in a traditional text book way, but there is just enough to move the story on. You see how the sisters played on gang-controlled tennis courts, hearing shots in the background, seeing a sea of white faces as they played their first games and up to the present time.
The illustrations are what make this story. The realism to an almost abstract look fills each page. You see inside their home as children and you see their unique style on the courts. The image of the multiple trophies both girls have won is a representation of what they have accomplished in tennis, but like the illustrations of the trophy themselves, teeters on the edge of over-the-topness. The richness of the colors blend into each other as well as jump off the page.
The audience for the book could be as young as four or five up to about eight. And while the text is slightly more difficult and could be for about a second or (low) third grade reader, the picture book format might turn them off. The audience would probably be more for girls who are into tennis or sports in general, but anyone could read/have it read to them. If the classroom was talking about black history, it could be used there, but the one-on-one reading format seems to be more comfortable.
