I've always had a little bit of a soft spot for Mary Bennet, even though in most adaptations of Pride and Prejudice that I've read and seen she is portrayed as thoroughly cross and unlikable. This book puts the focus on Mary, and I really enjoyed it. I thought the romance was sweet, and the growth that Mary shows throughout the course of the book was very enjoyable for me.
One small complaint was that, especially in the beginning of the book, the author would refer to events in P&P in relatively large detail. I would hope that anyone reading this book has already read the source material, which would make these passages relatively unnecessary.
Overall, however, I really enjoyed this book.
