a charming novel, but ...

In deciding to read the "daughters of Mr. Darcy," I expected to find important characters of Pride and Prejudice through a real suite.
I suspected that with such a title, Darcy and Elizabeth would go into the background as the heroines are their daughters. However, we do not even see Mr. Darcy hat or headdress of Elizabeth, just as their shadows are already abroad long before this story begins!
Moreover, nothing is known of what could have happened since the end of the novel by Jane Austen; not even an evocation.
With their daughters it feels spontaneous generation. It is true that the purpose of the author was not to tell their children at great length.
This novel is charming and well-written, engaging the girls, but it totally lacks originality: why, having made a rehash of Pride and Prejudice? Same frame, same character traits of the characters?

The author had she not enough imagination to create a real result in the continuity of Jane Austen?

I had the impression of seeing the Bennet girls in full force through their daughters and nieces with a redial and a mixture of their characters.
The beautiful Jane became the beautiful Leticia with the timid character of Mary Elizabeth Camilla, Lydia and Kitty are Georgina and twin Isabella. The last of the daughters of Mr. Darcy is a bit of a summary of all the Bennet, which ultimately makes the most original character.
Regarding their loves, Leticia is racing by a pastor as Jane and Camilla falls in love twice as Elisabeth (except it's a little more crispy). As for the twins, they take to their heels as their Aunt Lydia.
Mr. Darcy had enough hair pulling with his future sister in law: she and her daughters may fear that he became bald. Fortunately in the end it is far from it.

Finally, having wanted to pay a tribute to Jane Austen, the author is a little misguided and is on the verge of plagiarism, as is not Jane Austen wants. Hopefully his other novels, they are published in French will have the spirit required without being a copy too.
Still, the style that I liked, I think reading the adventures of Alethea.
