Standard Deviation, by Katherine Heiny.
I enjoyed this book so much. It’s been my supplemental Kindle read through the last couple-ish books I’ve been engaged with, and each time I returned to it, it felt like a vacation or a treat. The writing was sublime and so easy to fall into, and I even stayed for the discussion questions at the end. It also taught me something about decisions, satisfaction, and the concept of good enough, and the Sagittarius in me needs to be reminded of all of those on a regular basis. Very happy I stumbled upon this one when I did.
