When Fitzwilliam Darcy's sister lies dying from a magical ailment, the only person who can help is Elizabeth Bennet, the powerful Librarian of the Great Library - the same woman he abandoned five years earlier.

Elizabeth can't forget Darcy's refusal to believe in her magical ability, even now that she has a griffin familiar. However, as the Librarian, duty compels her to help him. Together, they undertake a quest to the Faerie Realm to find a cure, encountering dangerous magical creatures along the way.

An even greater danger lurks in their own hearts. After their heartbreak five years earlier, can they stop themselves from falling in love all over again? And what will happen when they discover that Georgiana Darcy's illness is intertwined with a danger that threatens all of England?

Mr. Darcy and the Enchanted Library began as an interactive group writing project. In response to enthusiastic readers, the authors have revised and expanded this second chance, forced proximity romantasy based on Jane Austen's Pride & Prejudice.
