Review:
For different reasons, both Caroline Bingley and Richard Fitzwilliam are obliged to remain in London during the summer. The lack of adequate company and entertainment during this time of the year makes them be frequently in each other's company, giving rise to a (in the author's own words) “decidedly un-epic courtship” which is told through a series of letters from the Colonel and Miss Bingley to their respective families.

The P&P fandom usually presents two versions of Miss Bingley: an absolute shrew that resents to the end of her days having lost Darcy to Elizabeth or a young lady victim of the society of her time that eventually comes to recognize the error of her ways and becomes a better, kinder person. While both characterizations can work well, one of the things I loved about "An Ink-Stained Year" is that Caroline is neither perfectly awful nor perfectly good. She has plenty of well documented faults, but also a number of qualities which may not be obvious at first. The same well rounded characterization is granted to Colonel Fitzwilliam, who is neither hero nor rake. Add to these intriguing characters the wonderful way the letters themselves are written (full of personal touches and historical details) and you have a fic which is quite different from what you usually find in the P&P fandom, but most definitely worth reading.
