“A play about currency during wartime, survival, and the power dynamic between protectors and the protected.”
Hunger by Meghan Greeley was such an interesting play. It is written in a way that is non-specific for the timeline, though they use candles and not very high tech equipment, and it is in a time of ethnic cleansing, so you can consider it taking place in generally any wartime in the 1900’s.  A middle-aged couple shelters a younger couple in their modest farmhouse, and when their guests' money runs out they welcome a wealthy teenage girl into the household. As food and other supplies run out, tension mounts. 
This play gets WEIRD. Definitely a trigger warning for sexual assault, power imbalances, and possibly gore. It took me a month to write this review because I had no idea how to do it justice. It really shows how desperate times can change people, and portrays good people doing morally grey things, to the extent of leaning towards morally corrupt things. At the same time, they are still protecting the three stowaways, something that could get them shot and killed. What kind of price can one put on safety?
I highly recommend it as something you should read, and then read again, and then sit and think about for a while. It’s short, at only about 80 pages, but the content definitely balances out the length.
