Here was my thinking in picking up this book: I'd read the first two so I thought, "Eh, there's only one more, I'll just read it to find out what happens." Then I found out at the end of Passion that the final book in the series, Rapture, will come out Spring 2012. Although I had never read anything saying the Fallen Series was a trilogy, I had assumed. Now I'm back in the position of "Eh, there's only one more, I'll just read it to find out what happens." So I'll do that next spring.
Anyway, I had read that Passion was going to be a lot better than Torment, which I mostly didn't like because the relationship between Daniel and Luce seemed so forced. I had read in someone else's review that Daniel redeemed himself Passion by proving his love. Well, to Luce he redeemed himself, but to me? Not so much. I still found their relationship tedious and overwrought with teenage angst. It doesn't feel like real love to me. That was what I didn't like about Passion.
What I did like about Passion was the format of the novel. Lauren Kate takes Luce on a journey throughout the novel, father and father back in time as she searches for meaning in her relationship. I am a history buff, and though the book wasn't exactly historically accurate in all ways, I really enjoyed seeing Luce's past lives. What I really enjoyed was that though Kate could have written the novel with all of the past lives taking place in American and Britain, which is probably what I would have been close minded to do, she took Luce all over the world.
Three stars! I have enjoyed the covers in this series and I can't wait to see what the cover for Rapture looks like.
