Although I loved Twilight, I was very disappointed in New Moon, and I only decided to read Eclipse because I already had a copy and was curious how Stephenie Meyer tied up some of the loose ends from New Moon. I'm glad I did. This book wasn't wonderful, but it was definitely an enjoyable, easy read (took me three days despite its 600 pages).
The book started off poorly with Edward being overprotective of Bella to the point of insanity. He's always been stalker-ish, but really, kidnapping? That's not a very healthy relationship. But once Bella was "allowed" to start seeing Jacob again, the story picked up. Characterization is definitely Meyer's strong suit, so although the plot line itself was predictable, the dynamics between Bella/Jacob and Bella/Edward were enough to make it a page turner. My favorite part was when Jacob serves as space heater for Bella in the tent.
My biggest complaint about this book is its length. I know Edward doesn't want Bella to become a vampire. I know Jacob is in love with Bella. I definitely know Bella and Edward like to make out. Does it have to be repeated over and over and over?
I would rate this series the same way I do the Harry Potter books - A for storytelling, B for originality, C for writing style.
