For a final installment in the series, I was rather disappointed by this book! Olivia and Michael developed emotions for each other much too quickly, especially in an intense and volatile situation. Much of the book was one action scene after another and it was rather unbelievable as well! The faith wasn't preachy or even overt, it was just kind of there. While it was a fast read, and tied up a few loose ends, I wasn't impressed with the book overall, and am glad I got the final two books from the library rather than purchasing them.
