This was a fun story. I liked the slow buildup with all the hints regarding Cassie's affliction, and the entire premise was well thought out. You did a good job of expressing important details and the characters' personalities succinctly without ever getting bogged down by it. There were some awkwardly phrased sentences, and the last full sentence felt oddly abrupt for an otherwise great ending, but the content was great throughout.

I am curious if the parole officer, who has the same curse, can be shrunken by Cassie (and vice versa)? Like, if they were together without their meds, would they both shrink or are they both immune to it since they're both cursed? I don't know if you plan on doing anything else with this setting, so maybe it doesn't matter, but having the cursed people stay together seems like a better solution than solitary confinement if they are in fact immune to other people's shrinking.
