3.5/5 stars.

This isn't the story of the virologists searching for a cure as their time runs out. This isn't the story of a brave hero in a post-apocalyptic society. This is the story of one very flawed woman and the things she'll do--good and bad--to help save part of humanity, and it's also the story of three sisters and their family.

Morris’s disease is a variant of the measles and it kills 1 out of every 3 it strikes, including pediatrician Dr. Isabella Gauley's niece Lisa Morris. When Isabella's mother Brooke brings an important discovery about Morris's to Isabella they hatch a plan to isolate and protect people haven't been exposed to Morris's and also those who can't be vaccinated. They keep this plan secret from their activist sister Angela who campaigns for mandatory vaccinations, a campaign that's been twisted to anti-abortion lobbyists to dispense with legal notions of bodily autonomy.

1/2 star off my rating because this novella had a lot going on and not enough space to show it all. There are moments, especially near the end, when I would have felt far more strongly about events if I knew these characters better. I really liked the details, especially what I mentioned above about the political landscape post-Morris's, but I didn't have enough time to enjoy them.
