I read the first in the series and had mixed feeling but I enjoyed it enough to request the second through LibraryThing. I was given an advanced reader copy so I cannot comment on the editing other than it was quite good even as an ARC.
I still don't agree that this should be considered a Christian book and I know that those are the books Revell publishes. This just doesn't line up with my beliefs, but with that aside, as a fiction novel, it is a very interesting story.
The characters are well developed and they are believable, just the storyline is not. But, it's a great fiction story not meant to be believable. This is the second book and is mostly centered around Ellen, the younger sister. The first book centered around Marian. I am looking forward to the third book which I'm guessing will center around their dad.
If you like good, clean fiction you will enjoy this book. Time travel is the main theme.
I do recommend this as fiction but not as Christian fiction. I give it a 4 out of 5-star rating.
