Jumpin Jackie, The Cow that Jumped Over the Moon, a children's book by Wisconsin author Jack May, tells the amusing story of a little calf who was born to jump. Although it was unusual for a calf to leap, bound and jump off the ground, Jumpin Jackie showed that with hard work and a great attitude, the sky was the limit! This charming children's book, illustrated by Jeremy Provost, is a great gift for Christmas, a birthday, or any special occasion!
