This has been lingering on my eARC list for a while and I finally read it! It's about motherhood in your 30s and how relationships change with the added dimension of LA's classist culture and a pretty strong anti-vax storyline, pre-covid.
There's a bit of a revenge plot that made me not 100% on the protagonist's side but I guess at least she's not just letting life happen to her. There are also some funny and/or absurd moments.
