Consider Astrophysics for People in a Hurry by Neil deGrasseTyson. Recommended by 2 sources.

“Tyson writes short, conversational chapters that translate cosmic scale, basic astrophysics, and the arc of cosmic history into vivid metaphors and brisk explanations. The most useful part is orientation—memorable anchors and mental images that make large ideas stick without equations. Annoying or limiting: frequent brevity means topics are sketched rather than developed, and recurring jokes or one-liners can feel surface-level. Best as an appetite-whetter or primer, not a deep technical course. Read in short sessions; it hands you curiosity more than instruction.”
