I wish my Dad had lived long enough to have this given to him!
Format: Paperback
As I said for Mr. Vansant's Gettysburg graphic novel, this is perhaps the best visual description of all of the planning, logistics, and follow-up battles that gave the Allies their second front, and began the march to Berlin, and the eventual downfall of Hitler's Thousand Year Plan.
I have studied War History for as long as I can remember - focusing mostly of the American Civil War, World War 2, and Vietnam; three of the United States' greatest turning points in warfare - but my Dad and I shared a huge interest in WW2, watching as many documentaries on it as we could. What most people do not know about the importance of the war is that it is one of the few times that most of the world was not only involved either directly or indirectly, but also it is one that everyone - and I mean everyone, from the footsoldiers, leaders, and civilians - knew exactly why and what they were fighting for. While it seems odd to refer to events so brutal as noble, that is the best way to describe World War 2, since most of the world was involved in it, and why.

10-year-old grandson loves this book
Format: Paperback
I bought this for my grandson who is very interested in World War II. He has just turned 10. He loves the book. It seems to be the perfect balance between text and pictures. He will learn about the experiences of his great grandparents while learning to read at the same time.

A+
Thought it did a really good job framing the big picture, as well as showing some of the nitty gritty details of the fighting that took place. Even though I thought I already knew a lot about D-Day, I still learned some things along the way.
Note: although I do most of my reading on my Kindle Paperwhite, I read this on my iPad Kindle app instead. I don't expect the graphics to come off too well on a non-tablet Kindle so did not even download it there.

Wonderful middle grade book
Format: Hardcover
This book is part historical fiction and part sci-fi. I bought because we like getting the Newberry award winner every year. We loved this story. It was fun read a book placed when I was kid and see/show my kids how much the world has changed, but it also had a fun time travel element. This coming of age follows a kid and his worries about Y2k. He deals with the death of a friend and worries about everything. We loved this story and it's special sections back i to the future making it easy to believe that time travel is real.

Fantastic
Format: Kindle
Time travel books are fun. You have to wrap your head around how they work out in the end. This time travel book sort of sneaks up on you, in that other things are going on while Ridge, the time traveler, is checking out 1999.
For those who were alive in 1999, we all worried about Y2K, when all the computers would stop working. Scientists worked hard to make sure that it wouldn’t, and at the time, only one bank had trouble after the new year began. Other than that, we were all fine, and life went on.
Micheal, is obsessed with Y2K, and when he learns that Ridge is from the future, it is all he wants to know about, and Ridge can’t tell him, as the event is too close. He can tell him how he got his name, and a little about how life is like in the future, but that is about it.
But Ridge is the first time traveler, and he has no idea if anything he says will change things, so he has to be very careful. He has no idea what he will find when she returns home, and so worries about everything he says.
I really enjoyed this book. I marked several passages that spoke to me. And even the title is such a good thing to bring up and explain, in that it means living in the present time. Not worrying about the future or the past.
