Book Reports / Conditions experienced by the slaves -CARNEGIE MELLON CHOOSE A SENTENCE TO DESCRIBE A BOOK [3]

Here is what I have. The book is about a girl escaping slavery in the US to Canada

I was horrified by the gruesome and horrid conditions experienced by the slaves, but I was truly amazed with Julily's courage, perserverance, and determination to escape captivity to Canada to free herself from shackles of slavery, even through hardships such as the separation with her mother.

PLEASE PROVIDE ME WITH HARSH CRITICISM

thanks!
