This was totally wild. Very short, but packed a lot in there. Estée lives through the most hellish childhood, the worst, most captive marriage, and a demonic baby spawn, making it through to the other side. The whole thing felt very Addams Family-esque in a fun way.
Part 1: Estée's father is an insane scientist who does horrible experiments on insects, working his way up to birds and small mammals, ending with human beings. Her mother believes she is paralyzed after having sex with her father for the first time, resulting in Estée and the apparent loss of the use of her limbs. Estée is kept completely captive in the house, banned from school, learning only species, genus, and phylum of all variety of animals and being forced to be her demented father's laboratory assistant.
Part 2: Estée is married off to the boorish, eighties-finance-bro Pete Magnus and finds herself out of one captivity and into another. She is completely guileless, knowing nothing about the real world or the nefarious creatures who inhabit it. Lights are shined on American excess. This part was the weakest. It's been done, of course.
Part 3: Estée becomes pregnant with a demon spawn, believing it to be the son of a shrunken head in Pete's showy tribal artifacts collection. This part was my favorite. The baby is born with a full set of teeth, eats rodents, claws at his fathers face, and leads his daycare classmates in a cult-like uprising against their abusive, disciplinarian teachers. I liked Little Bill, as he was called. He didn't speak in normal sentences, instead aping things he had heard on the news. "'A generation gap in venture capital,' said William matter-of-factly." Or "'Wild bachelor party with seventy-two topless girls,' he mumbled plaintively in her ear." He was like Sunny from Series of Unfortunate Events, where every nonsensical thing he said had an exact analog in more typical speech. Or the baby in The Addams Family Values, sweetly destroying, maiming, and torturing.
One blurb on the back posited that if Flannery O'Connor could come back from the dead, she would have written something like Omnivores. I disagree wholeheartedly with that bizarrely hyperbolic statement. More likely, if Charles Addams came back from the dead, got together with John Waters, and took a creative writing class taught by Ottessa Moshfegh, then that might yield this book.
