I picked up Of Moths and Butterflies for the low low price of Free on Amazon Kindle. From the description, I knew the book was set in Victorian England and it was about an entomologist/lepidopterist (Archer Hamilton) who falls in love with his uncle’s servant (Gina Shaw, aka Imogen Everard), a girl running from a scheming family, a scandalous past, and a fortune she sees as more of a curse than a blessing. Their marriage was arranged without her knowledge. The final paragraph of the blurb was: “Mr. Hamilton is about to make the acquisition of a lifetime. But will the price be worth it? Can a woman captured and acquired learn to love the man who has bought her?”
Some Spooky Shirley Jackson Novels
Shirley Jackson writes my favorite type of horror - creepy and ambiguous, relying largely on characters rather than violence or the supernatural.
