Coming of age book including ghost?? Read around 2016.

[Kevin]

I remember reading a book in my childhood, set sometime between the 1980s or the early 2000s. It featured a male protagonist and a female side character who became a ghost after dying in a parked car near a park. There's a scene where the characters hold hands, and at the end of the book, as the sun rises, a significant event occurs, possibly involving the characters disappearing. i’m sorry if it’s really vague i read it around 8 years ago thanks in advance ! been looking everywhere but haven’t had much luck

Kevin, how far into the book does the female character die and become a ghost? Do you think this is a spoiler?
