This is an excellent book, written very well by Laurence Fleming.
There are quite a few twists to the story, and there is a real bond between Mr Darcy and Lizzy (one of the sequel books I read made Lizzy out to be a timid woman who was unsure of her place at Pemberley and distrustful of her husband, but this book is so much better because they confide in each other often, and have a proper marital bond).
It's interesting for the main characters from Mansfield Park, Persuasion and Northanger Abbey to appear in the book.
Many of the Bennet sisters, Georgiana and even Mr Bennet (recently widowed) inter-marry with these characters which is mind-boggling at times but very interesting (for example, Mr Bennet ends up marrying Maria Bertram - whose brother Tom has married Georgiana - Tom's brother-in-law William Price marries Kitty Bennet, etc.)
All-in-all it is a very enjoyable read, perfect for taking on holiday or for a cosy winter's night-in. The hardback version that I have is a lovely size and quality.
I've now ordered the two books that follow on from this one - 'The Will of Lady Catherine
' and 'The Summer at Lyme
