"If friendship has an opposite it is war."

I Pledge Allegiance by Chris Lynch

Summary from Goodreads

Four best friends. Four ways to serve their country.

Morris, Rudi, Ivan, and Beck are best friends for life. So when one of the teens is drafted into the Vietnam War, the others sign up, too. Although they each serve in a different branch, they are fighting the war together--and they pledge to do all they can to come home together.

Haunted by dreams of violence and death, Morris makes it his personal mission to watch over his friends--and the best place to do that is in the US Navy. Stationed off the coast of Vietnam on the USS Boston, Morris and his fellow sailors provide crucial support to the troops on the ground.

But the Boston itself isn't safe from attack. And as Morris finds his courage and resolve tested like never before, he keeps coming back to a single thought.

He made a pledge. He must keep them safe

I mostly just picked this book up for the sake of research. Though the story held a lot of promise I didn't care for the writing style, lack of details, and shortness of the book. I felt like the story could have been a whole lot better with more of all of the above.

The characters didn't really have the depth I like with characters. I finished the book wanting more and ended up raiding the Vietnam biography section of the library.

Overall the book wasn't horrible. It did give me a glimpse into the Vietnam war. Also the series is about friends, so what can go wrong there. I do plan on finishing the series, I just can tell it won't be one of my all time favorites.
