The Darcy Connection by Elizabeth Aston

I preferred this story to Mr Darcy's Daughters. It is about Mr and Mrs Collins Daughters and their first London season.
These books all seem to follow the same formula, but, I find them to be fun quick reads.

Mr Darcy's Daughters by Elizabeth Aston

This book follows Elizabeth and Mr Darcy's daughters through their first London season. Lizzy and Mr Darcy are abroad and their daughters are staying in London with Mr. Fitzwilliam and his wife.
This is a fun easy read. If you are a fan of Pride and Prejudice you will probably like it. It is not the best writing, but, a fun story.
