I am already a confirmed lover of grammar. I have studied five languages besides my own and taken three linguistics classes, I've been writing for years, and I've edited many an essay. For the most part grammar comes instinctively to me. This book, therefore, is for me not so much a discovery as an affirmation.
The blurb on the back of the book compares it to The Little Prince, and it does have distinct similarities. Both books are about discovering the wonders of life. It also reminded me of The Elegance of the Hedgehog. Aside from having that indescribable quality common to all the French literature I've read, Jeanne's voice reminded me a lot of Paloma's in The Elegance of the Hedgehog. Two smart, matter-of-fact preteen girls.
I can see this being assigned in a French class, because it does a very good job of explaining basic French grammar. This is occasionally odd in translation, because the gender of words is part of the story and English words have no gender. The translation is never particularly jarring, though.
I loved this. It's short, sweet, French, grammatical, and wonderful. My favourite bit was the answer to the question, "What is a great writer?":
"Someone who, with no regard for trends and modes, constructs sentences solely to help him explore truth."
