Queer middle-aged librarian Nan Nethercott, a wisecracking hypochondriac with a lackluster career and a nonexistent love life, needs to make a drastic life change before it's too late. When she lands a job as librarian in a seemingly idyllic small town in southern New Jersey, Nan quickly discovers unforeseen challenges.

Nan's landlady, Immaculata, launches daily intrusions from below. The library, housed in the former town jail, is overrun by marauding middle-schoolers. A mysterious reader leaves distressing messages in book stacks all over the library. Thomasina, the irresistible butch deli owner, is clearly a delicious affair and not the relationship Nan craves.

There's no turning back though. Nan must come up with her own wildly unorthodox solutions to what the town and its people throw at her and fight for what she wants until she makes a shiny new life-one with her first true home, surprising friends, a meaningful career, and a promising new love.
