Granddaddy's Turn: A Journey to the Ballot Box by Michael S. Bandy & Eric Stein
From Candlewick Press:
Life on the farm with Granddaddy is full of hard work, but despite all the chores, Granddaddy always makes time for play. One morning, when Granddaddy heads into town in his fancy suit, Michael knows that something very special must be happening. For the very first time, Granddaddy is allowed to vote, and he couldn’t be more proud. But can Michael be patient when it seems that justice just can’t come soon enough? Based on the true story of one family’s struggle for voting rights in the civil rights–era South, this moving tale shines a spotlight on a dark facet of U.S. history.
