What is the setting of Hold Still by Nina LaCour?

The novel is set in Los Cerros, California, a small wealthy town in Southern California. Caitlin's home is in a nicer neighborhood, and she loves her yard, as it is large in size, although the house is simply large and new, as she describes it. Her school, Vista High, is also a wealthy school, and many of the children are from privileged neighborhoods. Like many smaller towns near larger cities, Los Cerros is far removed from big city life, instead preferring the cliques of a small town.
