OMG I can't believe I'm writing book#3! I know the cover doesn't add up to Guardian Herd but it was the closest thing I could find as far as a white and black unicorn fighting. Nightfall has taken half of One Herd to form an army. He heads for Anok for reinforcements will the pegasi of Anok bow down to this black foal? Or will they rebel against him too? In three months all of that won't matter for a war will come and will end in much bloodshed.
