As I sit at home thinking about my upcoming adventure and the things I need to bring, it makes me even more excited to begin my travel. I will be making my way around the world.

The first places on the list are Andalusia and Africa in the book The Alchemist. I will need to pack a lot of things and make sure I have enough money to provide myself with food and enough to drink. The Sahara desert is always hot and requires plenty of water.

Next I will head to Mexico in the book Born to Run, where I will meet the Tarahumara Indian tribe(部落). I will need to get into shape and do some jogging(慢跑) if I want to keep up with them. I will have to pack my running shoes, though, because the Tarahumarans have mastered the art of running on the tough land.

After Mexico, my journey takes me to the Egyptian desert in the novelThe Paris Vendetta. There I hope to help uncover an ancient conspiracy (阴谋) that goes back centuries. Just like my trip to Andalusia, I will have to make sure I have plenty of water. Packing the Camelbak products seems like the best idea, so I will have enough on hand at all times. I expect this adventure to be quite interesting, and I am very excited about it.

Lastly, I will make my way back to America in the book Shattered: Struck Down, But Not Destroyed. This makes me feel excited because like the main character in the book, I also wanted to become a professional athlete when I was younger. For this trip, I will go with an open mind and hopefully meet some friends along the way.

I am ready to embark on my adventure of traveling, and I cannot wait any longer!
