YA fiction, british girl with a weird name. boy across street attempts suicide

[Mena]

I wanna say her name was short, something like scout. there’s a big scandal with the boy living across the street and whether or not he attempts suicide. also a family in the cul de sac with a single dad and teenage girls who throw a party. also at some point there’s a older male character who’s the young girls teacher???

Mena, I notice your thread is marked Solved. Did you find your book, or should we move your request to the "Unsolved" folder?
