Ken's Moon is a fascinating book. The one thing I struggled with is the 'stripping' of the stars from the Moon surface photos as I believe during daylight stars cannot be seen in the visual spectrum either in Earth orbit, cislunar space (space between Earth and Moon), or from the surface of the Moon, (Google: at what altitude can stars be seen in daylight) (Look for scienceforums.com). Even so; a very interesting read.
