According to the Andre Norton Official Website, the artist for this book cover is by Laslo Gal, another favorite Ms. Norton book illustrator.
Here is another book cover and story that has heavily influenced me. As a reader. As a writer. As an artist. Breed to Come was the second story I read after 'Warlock of the Witch World' (more on that title later:)). This story was a milestone in that it not only featured what I would later learn to be anthropomorphic characters, but the level of world-building was astounding. In a nutshell, this is what would be considered a Dystopian sf tale. This is millions of years after earth was ruined and abandoned by the human race, who took to the stars, leaving a wrecked planet, the animals, especially the cats, dogs and rats, have evolved into separate civilizations. The story starts with a feline character and Norton explains his biology as if his remains were examined by scientific forensics. It's an incredible spare kind of writing that just took my breath away with its precision details! As Furtig (cat protagonist) explains, he is about to partake in some sort of ceremony to determine if he will be chosen as a mate. Norton has a knack for dissecting complex cultural and social mores into an interesting journey for the reader.
Furtig goes on a quest to figure out what his purpose is. But, this protagonist has another motive and so he decides to follow in the footsteps of a clan ancestor who pursued his quest for knowledge and was never heard from again. The story ebbs and flows. It picks up and slows down, especially by Ms. Norton's expositions on the landscape and what earth now looks like after millions of years of missing us. Of course, there is conflict and invaders touch down on earth to check it out as well. Furtig has to find his place in this new world and we the readers must figure out our place in this magnificent novel as well.
