The majority of the book Wintergirls takes place in Lia's father's home. This home is located in a suburban area of New Hampshire.
The setting is more than just a location. In Wintergirls, the setting also helps explain the plot themes.
For example, New Hampshire experiences extremely cold temperatures and wintry precipitation. This cold, snowy weather is symbolic of the pain, depression, and guilt Lia feels because of her anorexia.
Although the harsh New Hampshire location is a setting, it is also a symbol of Lia's emotional distress.
Lia spends time in other areas, as well. Amoskeag High is where Lia is a senior. While she should be focusing on her education and grades at the school, Lia's main focus is her weight.
New Seasons, the rehabilitation center, is another important location where Lia spends her time.
