SAMPLE BOOK REVIEW

Class- 11

The Diary Of A Young Girl; Anne Frank by Otto Frank

Review by: ____________. School: _______________, Class: _______ The title of my independent reading book is The Diary Of Anne Frank and the author is Anne Frank

but her dad, Otto Frank, published her book right after she passed away when the war was liberated.

Generally the novel that I chose is about the start of a diary of a young teenage girl named, Anne who

describes fairly typical girlhood experiences, writing about her friendships with other girls, her crushes

on boys, and her academic performance at school, because anti-Semitic laws forced Jews into

separate schools, Anne and her older sister, Margot, attended the Jewish Lyceum in Amsterdam. The

Franks had moved to the Netherlands in the years leading up to World War II to escape persecution

in Germany. After the Germans invaded the Netherlands in 1940, the Franks were forced into hiding.

With another family, the van Daans, and an acquaintance, Mr. Dussel, they moved into a small secret

annex above Otto Frank’s office where they had stocked up with food and supplies. The employees

from Otto’s firm helped hide the Franks and kept them supplied with food, medicine, and information

about the outside world. Otto Frank is the family’s sole survivor, and he recovers Anne’s diary from

Miep. He decides to fulfill Anne’s wishes by publishing the diary.

The main character of the diary that I read is Anne Frank and she was the protagonist who had

problems with few of her fellow classmates, but most importantly the antagonist of the story was the

Gestapo aka Secret Service of the Germans. The sequence of events that lead up to the conflict of

the story is based on hiding in an annex from the Gestapo, stocking up on foods, clothes, water, and

the things they need in order for them to survive.

I chose this book because I have a passion for history and I fell in love with The Diary Of Anne Frank

ever since I first read it so it wasn’t my first time reading it.

My initial reaction towards The Diary Of Anne Frank caught my attention to the point where I was

often thinking about it even dreaming about it, in which case, I was extremely fascinated about what

happened during the holocaust era. I feel this way because ever since I read The Diary Of Anne

Frank I loved history and every little aspect about it. The Diary Of Anne Frank is the best book that I

have ever read in my life and its not compared to any other books, its different and unique.

Yes, I would recommend this book to other people to read because it will make people realize that

there really is such thing as an innocent girl who believed in the world, but ends up getting dragged

with her family to the concentration camps for force labor work and then exterminated. Anne Frank

and Rachel Joy Scott had something in common, and Rachel’s challenge caught a lot of individual’s

attention by what happened to her, well that’s how I feel about Anne Frank.
