Is it me, or are small towns a sort of shorthand for certain tropes, such as...
- social immobility
- financial struggle
- depositories of dark secrets
- hotbeds of gossip
- places with horrible high schools

There's no denying that employing SETTING AS CHARACTER can be a powerful writing technique employed in books as diverse as Wuthering Heights and The Hunger Games. Beyond literature, it is instructive to break down cinematic examples of this strategy, such as Fargo, Breaking Bad, and Lost in Translation.
I recently read and enjoyed two novels set in small towns: PANIC by Lauren Oliver and ALL THE MISSING GIRLS by Megan Miranda. Though one book is an adult murder mystery and the other a young adult novel, both crossed into thriller territory and both are decidedly and critically set in SMALL TOWNS. In PANIC, the town is Carp, while in ...GIRLS, the setting is Cooley Ridge.

As you write your manuscript, it might be worth it to pay attention not merely to ways that place can set a tone or evoke emotion, but to ways in which place drives action. Consider:
- Do characters' manners or other behaviors change due to place?
- Does being in a given setting impact characters' value systems?
- If a character had been absent from a given setting, how might your story--and your world--be different?
- Is your place a starting point or a dead end?
- How does the setting impact characters' sense of self?
In skilled hands, place can serve multiple functions without the need to complicate the story with extraneous secondary characters. It can be a rainy paradise or a rainbow-hued prison. It can drive a character to madness or lead a character to unexpected love.
Make a list of small-town settings from novels you have read. Do they fit the trope parameters described above? Does the author use the setting to do more than establish mood? What can your setting - be it small town, big city, or something entirely different - do for your writing?
