One part of the book that I love is that it is realistic. Like how some things in it would happen in real life. In some stories say you find a dinosaur bone and a man comes who just happens to be a paleontologist. The chances of that are very high but this story didn't have anything like that so it was great.
The Next part of the book that I love is the plot line. In my opinion Underground to Canada has a very good plot line. I like how in the end Julilly is reunited with her mom and how she also meets Lester in the end.
Awesome Plot line
The final part of the book that I love is the characters. I like how the characters react like anyone would in their situation. They aced normally and coolly not freaking out by fear knowing that they could get caught, whipped or shot.
