Does this sound like a good story?

Rosa is a 15 year old girl living in berlin and the year is 1935 and it is the height of adolf hitlers power. Rosa does not agree with the nazi policys and is a member of a young resistance group. the story follows her life from age 15 to 24 and how her life is affected by the nazi's and how she witness's key events of world war two and the holocaust (e.g kristellnacht and nuremburg rallys). Its called beyond the willow tree and her and her bestfriend Bruno find a secret lily pond hiding behind a curtain of willow leaves on a willow tree and it becomes a place where they can escape the reality of life in Nazi Germany. let me know what you think honest opinions please and let me know if you have any suggestions.
