A book that disappointed you.
– Mansfield Park by Jane Austen. And I quote, “Scarcely had he done regretting Mary Crawford, and observing to Fanny how impossible it is that he should ever meet with such another woman, before it began to strike him whether a very different kind of woman might not just do as well, or a great deal better; whether Fanny herself were not growing as dear, as important to him in all her smiles and all her ways, as Mary Crawford had ever been; and whether it might not be possible, a hopeful undertaking to persuade her that her warm and sisterly regard for him would be foundation enough for wedded love.”
There’s nothing natural about marrying your cousin (incest). And I wish a different idea had struck him at this point.
