Across The Universe by Beth Revis

A love out of time. A spaceship built of secrets and murder. 

Seventeen-year-old Amy joins her parents as frozen cargo aboard the vast spaceship Godspeed and expects to awaken on a new planet, three hundred years in the future. Never could she have known that her frozen slumber would come to an end fifty years too soon and that she would be thrust into the brave new world of a spaceship that lives by its own rules.

Amy quickly realizes that her awakening was no mere computer malfunction. Someone-one of the few thousand inhabitants of the spaceship-tried to kill her. And if Amy doesn't do something soon, her parents will be next.

Now Amy must race to unlock Godspeed's hidden secrets. But out of her list of murder suspects, there's only one who matters: Elder, the future leader of the ship and the love she could never have seen coming.

I have finished the whole trilogy, but for now, due to a time crunch I will only be reviewing the first book.
Non-Spoilery
I gave this book four stars. I really enjoyed the world building and didn't have many questions about why things were the way they were, and trust me, they were answered in the second and third books. Amy was really defiant and rightfully questioned everything that was different in this new environment she was in after she was melted and woken. She seemed like the strong one in this couple, and it was refreshing to see the heroine take the lead. Elder was hesitant to question Eldest, and understandably so, however, I feel like he could have argued less with Amy. The whole sci-fi idea of this spaceship, Godspeed, traveling to this new and pretty much unknown planet with the shipborns and the Sol-Earth people frozen beneath (I am almost positive  that they call our Earth Sol-Earth) the main levels of the ship. Also, the mystery aspect of this book was really interesting and although I had a list of suspects (with the person who actually did it on the list) I was very surprised to find out the reason the frozens (like Amy) were being unplugged. If you haven't read this book, you should! Even if sci-fi or mystery aren't your things, like they aren't mine, you will still find yourself really liking this book.
