Great Start
Format: Hardcover
My 9 year old doesn’t like reading. When it’s time for him to read to us, this is his go to book. Chapter books are a bit intimidating for him. He is eager to read about Max and is wanting to ready without us asking. We are looking forward to book 2.

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.
