Reply #5: If you want more insight into her life

[SemperEadem]

try to get a hold of copies of her personal correspondences with her eldest child, Victoria, Princess Royal and Empress of Prussia, edited by Roger Fulford. You can find them mainly in online used book stores. You'll find whole lot of insight into her thinking and especially her "madness" after the death of her husband.

There are some books out there on ERII; I've read some biographies of her great grandmother, Queen Alexandra and her grandmother, Queen Mary. They offer some insights into her as a child.
