Dew,
Any time travel primers this little girl should be reading or anything you think will help dumb this all down for me?
There are "lots" of books that you can read that deal with the subject as pop-sci/non-math. I'll give you three that you can find on Amazon, Borders, etc.:
"Relativity: The Special and the General Theory", Einstein, Albert, PhD
It's a paperback. Einstein gives a very good overview of the subject of both of his theories. It's geared for the high school level reader. Very easy reading.
"Faster Than Light", Herbert, Nick, PhD
Dr. Herbert lists just about every known theoretical possibility for time travel, does a great job explaining each concept and gives the pros and cons as to their applicability in the "real" world as we currently understand it. Also geared for the high school level reader.
"A Brief History of Time", Hawking, Stephen, PhD
The classic paperback written in pop-sci terms for the high school level reader. It deals with general realtivity lightly and delves into the mystery of black holes and how spacetime is affected by the gravitational field surrounding the hole. Easy reading.
There are many other books that deal with the subject in terms of the calculus behind the special and general relativity. They're still pop-sci but are written for the college level reader.
When you're ready you might want to take a step up and try:
"Six Not-So-Easy-Pieces", Feynman, Richard, PhD
It's also in paperback. This book takes six chapters out of his three volume four semester undergrad physics course at CalTech (in the 1960's). Some basic algebra and differential calculus but it really doesn't get in the way of the text because he was also a very good writer. The chapters in the book that deal with special relativity are what you would be looking for.
A bigger step up:
"The Special Theory of Relativity", Bohm, David, PhD
Another paperback that deals with special relativity in terms of the math (basic differential calculus) - lot's of math, in fact. He has a very interesting chapter at the end of the book that deals with physics and perception in terms of early childhood development. Great chapter.

It's a good thing that some PhD's decided to write pop-sci books on the subject for the non-scientist. Time travel is not an easy subject because it flies in the face of our intuition of how the "world" works. The world that we can see, touch, hear, etc. appears to work as described by Newton. But when we encounter extreme gravitation or extreme velocity we discover that our intuition is wrong.
