The book is a collection of five stories following the same characters in different time periods from the 60s to 1999. There are differences in narration in each story, and some of them present paranormal elements, which is great. Still, I don't think any of the stories can be considered a horror tale. They are emotional stories, I dare say. The first two tales are the longest and the ones I definitely enjoyed the most.
In "1960: Yellow Card Man", the story follows Bobby Garfield, the only son of a widow who doesn't appreciate him much. At the beginning of the story, a new tenant arrives at the apartment building where Bobby lived: Ted. Bobby and Ted start a friendship that begins by talking about books (And how they talked, wonderful) and becomes deeper and deeper as the story progresses. The tale is full of action, funny moments, suspense, disturbing scenes... it has everything. The characters, who will be repeated in the other stories, are great and realistic. Really a great story.
In "1966: Hearts in Atlantis", Pete Riley is a scholarship student at a public university where the card game called "hearts" starts to become a problem for his studies. In this story, Carol, a friend of Bobby, makes her appearance six years older than in the previous story. This is the story I enjoyed the most of the five. It's the best, the story seemed like it didn't amount to much, but it did. The narration is a wonderful and powerful thing. I love it, it's just... great.
I can't give a synopsis of the other three stories because there would be spoilers for the first two. They are somewhat short and rely a lot on the previous events to build a plot. The third one is the most interesting. The other two were also very good, because I could say they are like extra chapters to the previous stories. There is extra information.
Overall, the book is really good. It gives a very interesting view on the Vietnam War. The characters have a great evolution, the stories are emotional. The narration is fantastic. Great, great book.
