All Cats Are Gray

All Cats Are Gray by Andre Norton is a haunting and imaginative science fiction novella from the 1950s that delves into the mysteries of space and the power of perception. Follow the enigmatic Steena, her loyal cat Bat, and down-on-his-luck spacer Cliff Moran as they investigate the ghostly derelict spaceship Empress of Mars. Steena's colorblindness—seeing only in shades of gray—proves to be the key to unlocking secrets invisible to others. With themes of isolation, intuition, and the unexpected strength found in companionship, this classic tale explores how unseen truths can shape destiny and how even the most overlooked individuals can become heroes in the vast unknown of space.
