The third installment in The Rise of the Penguins Saga. THE STRUGGLE CONTINUES... Since the fall of the Overlord, Nok and the penguins of Rockhopper Colony 23 have fought bitterly just to survive. Nok, the colony's leader, is plagued by dissent and distrust at every turn as the colony battles to regroup and stabilize. But something far worse lurks below the safety of the warrens, and Nok's political rival, Lydeck, may raise it. Only a pair of fledglings stand in Lydeck's way...if they can survive long enough to fight back.
