Disclaimer: all the opinions are my own, and if you like this book, I am happy that this book met your emotional needs. Now straight to my ranting.
Oh, boy, it was so sub par that I had to return my Audible book, and I hardly ever do this even though I have been an Audible member for 7 years. I also think that I have been conned ... by publishers, by book marketers, and by the book cover ... Yes, I am willing to admit that I am stupid like that.
The book is marketed as WWII historical fiction ... Mildly speaking, this might qualify as historical fiction as the events took place during WWII, but I wonder what happened to one of my favorite genres. Recently, it has become a place for everything lackluster in the publishing industry. Romance is often masqueraded as historical fiction; Christian fiction is often marketed as historical fiction; some preachy books are often marketed as historical fiction. There is a reason why ... There are still good historical novels that tell us the stories of the past while romance novels and Christian historical fiction are often nauseatingly baaaaad. So, it is a nice gimmick to sell books under the umbrella of historical fiction to make more money. Mea culpa - I simply should have researched better! As the numbers show, it looks like I am in the minority here as the majority of the people love the book, and the book found its audience, but I was not its intended audience.
As for me, I found the dialogue stilted and primitive. It sounded as it was a bad YA book with clumsy overstated and over-explanatory conversations. In addition, the characters were all unbelievably flat and very formulaic. Somehow, Ruby was surrounded only by good people, and there were no bad guys around her. The only semi-grey character was her husband, who was trying to shelter her by not telling her that he was in Resistance, but guess what - he is described as insensitive and callous because of his clumsy attempts to protect his wife.
All the other characters ( if they were characters and not just the soldiers marching by) were people who sacrificed their everything to undermine German efforts. So tell me how it works in the world of big numbers that if everyone you know is against the Nazi even at the Nazi camps and in Germany, how come the world had succumbed to the deadly cancer of fascism? It would have been rationally impossible, but somehow Ruby lives only in the world of angels who are confined to live in the world of the Nazi.
Now ask yourselves how realistic is the next part. Ruby repeats repeatedly ( I know the tautology is bad, but I can not help myself imitating the author's style) that she is not very religious, but she prays all the time, and she does not forget to mention that she is a Catholic right into a reader's face ... multiple times.
Plus, her perennial wonderment every times she got pregnant made me roll my eyes quite loudly. Really? Why did it come as a surprise? Plus, why did she give birth TWICE while she was asleep? On the other hand, we are also dealing with the precocious Charlotte who knows the answer to all questions, and her thought process is inconsistent with her age.
Another thing that kept nagging me is sustenance. Did Ruby work? How did she survive? Where and why did she get the ration card? Did they give them to everyone in Nazi occupied France? Was Paris one big commune? Or is it a poetic license to not discuss social issues and believe that the character can live out of space and time of earthly needs?
The only consistent thing is a plot. It is not exactly the believable plot, but at least it has the modicum of consistency.
Let me be quite informal but blunt here - do not read this book if you have high literary expectations. The prose is pedestrian, and the writing is immature, and the book is not what it seems to be. If you like to be shown not told, then this book is not for you. If you like when the author uses different words to express similar concepts, then this book is not for you.
Finally, if you want to read WWII fiction that will haunt you in its beauty and pain as good books should, please read The invisible Bridge by Julie Orringer.
