One of my favorite series from the past was the "and me" series. This series is about a kid who travels in time with baseball playing cards from the past by holding them for long enough. But the only way that he can get back to present day is by using a present day card. But the only way that he figures this out is from the book Wagner and Me. This book was the first time travel that he had every made to meet Honus Wagner. He didn't know that he had the power to travel back in time with his playing cards until he had held on to the card for long enough to end up going into the past. Usually he went back in time to make money in the future but his main reason was to just simply meet these players. When he met Honus Wager he had no clue what he was doing so when he had decided that he wanted to go back to present day he didn't know what to do. But then he figured that he had to have a present day card but he didn't think that he had one....
I thought that this whole series was awesome because at the time that I had read this I was very into baseball and this was so interesting to me how he had traveled back into time to meet these amazing players.
Over all I love the author Dan Gutman who wrote this whole series and I wish that he would add more books to it but I don't think that he is going to because he has not written one in a while.
