In a basic sense, 'A Little Life' is a homage to how my friends and I live our lives. I wanted to push past the definitions of how we typically define friendship. It's a different version of adulthood, but it's no less important and no less legitimate than anyone else's.
The nice thing about publishing later in life is that you already know who you are. You don't have to hang out with the 'Paris Review' crowd to try to make yourself feel like a legitimate writer.
