In the second book of the Mesaland Series, Baby Jack grows up and is renamed Hop-a-long. Hop-a-long and his sister Jumping Jack leap across the mesa and get into plenty of mischief. On moonlit nights, Jumping Jack likes to hop on the smooth sand beside the mesquite. And Hop-a-long prowls the mesa, spying on his prairie dog friends and hiding from Hungry Owl.
