The book for July is Horse: A Novel, by Geraldine Brooks.

From the publisher: A discarded painting in a junk pile, a skeleton in an attic, and the greatest racehorse in American history: from these strands, a Pulitzer Prize winner braids a sweeping story of spirit, obsession, and injustice across American history.

Based on the remarkable true story of the record-breaking thoroughbred Lexington, Horse is a novel of art and science, love and obsession, and our unfinished reckoning with racism.
