Help! I can't find a lesfic book title and I'm starting to wonder if I made it up, haha. What I remember:
- One of the main characters is a teacher
- It's toaster oven-ish
- She goes to another teacher as a lesbian guru
- The other main was a businesswoman of sorts, may have showed up for career day
- A character had a child and was going through a divorce
- Writing felt like Melissa Brayden or Georgia Beers
