You can always tease parents with the adage that the apple doesn't fall far from the tree.

I'm one of the legions of people who owns but has not read Stephen Hawking's A Brief History of Time. Heck, I even own but have not read a handsome, hardbound, cased set of The Feynman Lectures on Physics, a comp from my days as a publishing sales rep that I didn't want to give up. So, to get me started, I'm attracted to Einstein Adds a New Dimension, by Joy Hakim. The reviewer suggests the title for Grades 7-12, right where my physics education left off, and notes that it's for readers "who enjoy having their intellects stretched" (but not broken).
