Cattle Cars

So i read this book for school called "Between Shades of Grey." This book is set in 1947 and it is about the NKVD, who work for Joseph Stalin, taking innocent people putting them im disgusting old cattle cars and taking them somewhere to get sold, but one group does not get bought so the NKVD take them up somewhere to work and then eventually they go up to siberia. The main characters name is Lina and she is in love with a boy who is in the cattle car with her who's name is Andrius. So for school we had to pick a character and write in first person as that character about their journey in the cattle car. I chose Andrius, so that is what i will be writing about.
