Wrinkle in Time?

[franspeakfree]

On my quest this morning looking in to how time space is theorised in the 4th dimension using the tesseract as a model I came across this - Wrinkle in Time

Has anybody here read it? - It is a science fiction novel regarding dimensional travel under the code name tesseract, written in the 60's.

Looking at the sample, there are some clear parallels to modern day metaphysical science brainstormning. It is clear that the author has done her research, or as I suspect she was given a helping hand.

In fact...  I have read it at least 5 times, starting at about the age of 13.

Marvelous work, and nothing in there that seemed "fantasy."  Highly recommended reading albeit a "juvenile" - a work produced for young teens.
