All Hallows Eve by Wendy Sotis
In this Jane Austen fan fiction the story is quite unique.
While Darcy is torturing himself as he has realised he loves Elizabeth even though her standing is so inferior to his own. He walks to clear his head and on hearing Elizabeths lovely voice finds her in a clearing performing an ancient ritual.
Everything he knows is turned on its head. He and Elizabeth are linked and she is the one that out ranks him.
She is a high priestess and it is his destiny to protect her, she is in terrible danger.
Darcy enlists the help of Richard Fitzwilliam and his older brother as well as Bingley to be guards for Lizzy.
I don't want to give away the story, but, it is full of action and excitement Loads of danger for Darcy to save his Lizzy from and some very neat twists that put some of Jane Austen's characters into a completely different light.
This is not for you if you are a purist but it is a lot of fun. And, having read this I shall have to find more books by Wendi Sotis to read as this one has really whetted my appetite.
