Dead space salvage final?

I enjoyed the book for its great story telling and its developing of characters. Though the setting/ story were kinda vague it did tell a good story with the characters in the book. I feel that the author of this book isn't trying to get anything across the reader other to be shocked. But I think this book is symbolic in a way. Because of how the characters are separated almost definitely into classes and how there's a psychotic religion that most likely raises the dead. I'll try to find more to back this up.
