A young girl finds her voice--and discovers the power of speaking up for herself and her community--in this sweet and humorous chapter book by award-winning and #1 bestselling author Kwame Alexander, perfect for fans of Ivy + Bean and Ruby and the Booker Boys. When Macy gets book one of The Mighty Zora series for her birthday, she stays up until 11:34pm finishing the book. But the next day, when Macy gets to her school library, eager to check out book two, she finds the door locked with a sign explaining that the library will now only be open a few days a week due to budget cuts. Even worse, she finds out her father won't be home to help her figure out what to do, as he will be traveling to a museum in Montgomery, Alabama to read a poem about civil rights. With help from her fellow third graders, support from her mom, and encouragement from poems written and hidden for her by her father, Macy must find her voice and learn the power of advocating for herself and her community. Can Macy learn to be Mighty?
