Across the Universe was enjoyable, but nothing truly special to me. No offense meant to the book, it caught my interest and I wanted to know what happened next, but it seemed overall predictable and one of the two main characters drove me nuts. 
 A Million Suns is so much better. Elder is much more relatable and I even went as far as liking him! The plot caught me and stuffed me in the trunk of car and refused to let me breathe for air until I was finished. So good. It was still a tad predictable, but it was incredibly enjoyable. 
 I highly recommend this one, if you enjoyed Across the Universe, this is even better, and if you felt meh about it like I did, you'll probably find this one to be so much better.
