How humans experience eclipses, writes astronomer and physicist Nordgren (Stars Above, Earth Below), lies at "the intersection of fear and calculation, mysticism and science." Nordgren explores that intersection with aplomb, weaving digestible astronomy lessons and helpful illustrations into stories of eclipse appearances throughout history—along with his own travels with fellow "eclipse chasers" around the world. Solar eclipses especially, with their momentary darkness and diamond ring effect, have long been viewed with equal parts fascination and dread. Cataloged by the ancient Egyptians and used for navigation by Meriwether Lewis and William Clark, eclipses were even used by 19th-century astronomers to search for the elusive planet Vulcan before Albert Einstein's new theory of relativity rendered it nonexistent. Anticipating the "Great American Eclipse" in August 2017, the author offers tips for viewing and suggested supplies, along with a handy schedule of future events for intrepid readers. The mix of memoir and history is clumsy at times, but the author shares an infectious enthusiasm for the singular yet eerie delight of catching a glimpse of "totality." VERDICT A breezy yet substantive appreciation of a rare and beautiful celestial phenomenon, ideal for astronomy nuts and fans of popular science.—Chad Comello, Morton Grove P.L., IL
