I grew up on the James Mason movie, "Journey to the Center of the Earth" (1959), so it was quite a shocker to read the book. You could imagine to my dismay the absents of quite a few characters and the center of the story is Germany not Scotland.
Now for avid readers you could care less about old movies, I can truthfully say that this is one of Jules Verne's best stories and well told.
What you will find more interesting and fun about this tale is the characters and their interaction. One of my favorite parts is when Harry who did not want to go to the center of the earth with his uncle, Professor Hardwigg; he turned to his affianced, Gretchen, and was planning on her to stop him. Her answer is shockingly disappointing to him.
"While there is life there is hope. I beg to assert, Henry, that as long as man's heart beats, as long as man's flesh quivers, I do not allow that being gifted with thought and will can allow himself to despair"
Be prepared as the bulk of the book is really a geological journey back through time and forward again painfully spelled out by Harry whom is the first person narrator.
The Kindle version does not have actual picture of the runes in chapter 1. Moreover, a tad off on pronunciations. Other than that, it is more than worth obtaining along with a hard copy for your library.
