12 year old Jamie is the youngest of two in her family. She is 13, her brother is 18 and just joined the army to go be a medic in Vietnam. Since her father is a Colonel and she's been an army brat all of her life, her brother going to war excites her. She wishes she could go too. She's the only one, besides her brother, who is happy about it. When her brother starts sending her film of pictures he's been taken in Vietnam, she learns to develop them and see the war in a whole different way. He also takes pictures of the moon, which is something he did at home, too. She starts worrying about her brother and realizing that the war is not this great thing. She also forms a friendship with a Private Hollister when she starts working at the vet rec center. They play gin rummy together and start up a competition.
This was a short book, and for the most part it was okay. However, there was nothing very original in the book, the characters lacked the depth they needed to make this a better book (probably due to the shortness of the book), and it bugged me that I kept picturing Jamie as younger than her reported 13 years.
