Nelvana of the Northern Lights

"First appearing in 1941, Nelvana was tasked with protecting Canada's northern lands. Using the powers of the northern lights, Nelvana could fly at incredibly fast speeds, become invisible, and even turn to dry ice! She used her great powers to ward off Nazi invaders, shady fur traders, subterranean mammoth men, and interdimensional ether people. With the aid of her brother Tanero, a demigod cursed to appear as a Great Dane, and her sidekick Mountie Cpl. Keene, Nelvana was a steady force for good for six years before her adventures came to an end in 1947. Nelvana's complete adventures have been collected and reprinted in one single volume!" -- Back cover.
