Once Review by Emmy

Review by Emmy

Once is a beautiful story about a young boy's experience growing up secretly Jewish during the Holocaust. There are a lot of really interesting and intense moments in this book, and it makes it hard to put down! The protagonist Felix, is very easy to sympathize with, and so you care a lot about his feelings and his struggles. I really liked the way that the first person perspective was used, it was almost like you could see into Felix's brain. If you are a fan of intense stories with a lot of emotion in them, I can almost guarantee that you are going to love Once!

Good

Review by HKrischer

It is good, but not great because it is a little creepy, and wrong about what not to do and what to do if you’re Jewish.

ONCE A SAD STORY

Review by SweetiePye

you do not want to be Felix or Zelda in 1942. Poland was invadid by the Nazis. Felix is in an orphanage and than......you will have to read the book!😲
