Suspense throughout my book

The book I just finished, Across the Universe, was really good and the ending was not what anyone would have expected. The author did a really good job of building suspense because of all the cliffhangers during the entire course of the book. Also, you could sense that tension was building between some of the main characters and could tell that something was going to happen. I think that the authors way of building suspense was effective because it was settle enought that you did not think something big was going to happen but there was enought that you wanted to keep reading to see what would happen. She never hinted at what actually happened at the end so that made it even more surprising and an even better conclusion to the book since there is not a sequel. Overall, I think that the suspense in the book was what made me keep reading it.
