Okay. Second book. Wow. Even though this is a prequel to Mary Shelly's classic Frankenstein, I have rarely read such a unique and original story. The plot of this book relies more on the supernatural than the science and alchemy of the first book. Victor and Elizabeth travel to the spirit world, a place speculated to be limbo. Although there are many alchemical experiments, we soon discover that there are many more mysterious forces in play. Demons and angels do battle, the dead fight the living, and this is an overall pretty radical tale.I think that character development is something that Mr. Oppel is lacking in his books. It's a bit as if he sets a certain personality for each character at the beginning of the story, and they stick to that personality without change. Other than this however, I find Mr. Oppel's writing to be unique and captivating. He is definitely one to write a story and make it great.I have absolutely no idea if there will be a third book in this awesome series, but if there is, I definitely know of one guy who will be happy. *points to self*-Austin
