While there were not many grammatical mistakes, I found that there was a bit too much description. This made some sentences long and wordy, and it overall filled the book with unnecessary lines that started to almost distract readers away from the plot. Some amounts of description are good, but one can have too much description as well. In addition, much of the dialogue was a bit drab and slow. I would recommend that French try to give the characters a bit more personality.
I would give this book a two out of five stars. While the concept the story was trying to get at was interesting, the way the book was crafted could have been better.
