It’ll be a big day in Park Slope the day the sequel to Prospect Park West, Amy Sohn’s satiric novel about Park Slope moms and dads, comes out.

Her new novel is called Motherland and it’s about five mothers and fathers in Cape Cod, Park Slope, and Greenwich Village, according to the Amazon blurb, “who find themselves adrift professionally and personally.”

This week in The Awl, Amy Sohn has written an essay called “The 40-Year-Reversion” about what happens to contemporary parents when they need to chill out from all the stress and boredom of contemporary parenting.

“Why do moms in my generation regress, whether by drugging, cheating, or going out too late and too often? Because everything our children thrive on—stability, routine, lack of flux, love, well-paired parents—feels like death to those entrusted with their care. This is why they start drinking at wine o’clock, which is so dubbed not only because it coincides with whine o’clock but because it can begin at six p.m., or five, or even four. (Though the four o’clock mothers wind up in A.A.) I know a mom who drinks only on the weekends because she thinks it’s more responsible… but she starts with a mimosa at brunch on Saturday at eleven, and doesn’t stop until her Sunday night television shows are over.

She goes on to discuss her new novel, “The characters are inspired by my neighbors, who seek liberation not through consciousness-raising and EST the way their mothers did, but through Fifty Shades of Grey and body shots. They arrive home from girls’ nights at three a.m. on a weeknight and then complain about hangovers at school dropoff.”

Motherland comes out on August 14th.
