The book 13 Reasons Why doesnt specify the location of this tragic suicide but it mentions it's a small town with a 400 senior class-Cresmont High School.

She's new to that town but most of the main events that caused her to commit suicide take place in the following places; Post office, Blue Spot Liquor, EisenHower Park, Rosie's Diner, Gas Station, Party House, Monet's Cafe, Crestmont Movie Theater, and the houses of other people involved in her decision of committing suicide.
