Going into this book, I was afraid it was going to be one of those very technical science fiction stories that goes deep into how the technology works and uses and endless amount of jargon that I hardly know how to keep up with. Thankfully, it takes a more  philosophical tone as to what makes us us and going beyond our physical self to see what is at our core. 

Jessica may not be the protagonist for everyone. She starts the story as your typical teen with an attitude but gradually you get the context and you can start to see more of her perspective.  

I'm thankful that the story didn't slide into the easy trap of having a romance solely because there's a boy that's the only person her age on the ship. Their relationship is more grounded as a platonic one and really just grounds the story as a whole.

There are a couple of plot threads that seem to dangle and go nowhere.

?What exactly was causing the corruption of the data? Was it the "alien ghost?" Why did only affect her father and not her mother? How exactly was that data corrupted?

. The story just sort of ends without giving much closure to anything. It could have used maybe a chapter or two to give some clarification or tying of loose ends. 

Still, I didn't find it an uninteresting as I thought it would, even though some of the mysteries stay mysteries.
