Across the Universe is about Amy & Elder, two people who unexpectedly meet. Amy is a passenger on Godspeed, but she's frozen in ice because this journey takes over 300 years. Elder is the son of the "captain" of Godspeed, and is next to become Eldest. They meet when Elder unplugs her chamber, causing her to melt. What happens with Amy and Elder, and will they reach across the universe?
This book was very, ahem, inappropriate for a young adult. I definitely would not recommend this for younger readers. There's a lot of talk about mating, which is necessary for the ship's survival. I also thought it was a little dull and boring because so much of it focuses on Amy in her cryochamber. However, I do plan to read the sequel because I don't like to leave a series unfinished.
