Not so great unless you are willing to accept a certain amount on faith.
Format: Paperback
Similar criticism to my review of the Black Holes book: "Starts off ok, but quickly loses you. I have an extensive science education and quickly got lost. This topic cannot be easily explained in a brief book - the author is forced to jump over certain building blocks, and that just leaves the reader confused. I think this book series is good, but maybe not for abstract science topics."

A fun read. Learned a lot.
Format: Kindle
I never expected to be able to understand Relativity or the more ethereal concepts of time. But Jenann brought them to my level. The language gets a bit flowery at times but I think that reflects that these ideas have a poetry of their own.

Clear, Concise, and Compelling
Format: Kindle
The author takes us in an extraordinary trip through and about time. In particular, the discussion about Einstein’s Special and General Theories of Relativity were illuminating, clarifying a complex aspect of the nature of the universe. How should we think about time? This book will help the reader arrive at answers to that question.
