No, it was earlier than that (sometime in the winter of 2009-2010, I think), and it was in Bitches. Basically, the Elsie books were written as an example for kids of how to be a good Christian child. Elsie was always Good, and cried when she felt like she hadn't been as patient as Jesus would have been, and was quite certain in her faith. The main plot of the first two books is that her father, who's been traveling the world for most of her life, comes back. And he's not a Christian. (Meaning, he hasn't been born again.) And Elsie is desperate to win her father's love (in scenes that are written in ways that sound really creepily sexual to modern readers), and also to make him a Christian. Then there's one Sunday when he has a headache, and he wants her to read him a novel. She says that she'll read him the Bible, but won't read a novel on a Sunday. He punishes her, she won't relent, and it escalates until he says that, unless she apologizes and swears to do whatever he says, he'll send her away to Catholic school. Elsie then falls into a fever, and spends the next twenty pages or so delirious, moaning, "I won't bow to idols! I won't pray to Mary!" Then she dies. Then her father realizes the error of his ways, and accepts Jesus into his heart. Then Elsie comes back to life.
In the later books, Elsie marries her father's best friend, and they have a bunch of children. After a little while, the author seems to have forgotten that books are supposed to have plots, and also totally freaked out about immigrants, and so the later books pretty much consist of the family members telling each other heroic stories about the American Revolution, and worrying about how immigrants and Catholics and Mormons are going to destroy this great tradition.
Oh. And there's also a scene where Elsie tells some little black children that, in heaven, they'll be white.
