Who Did It?

Not good with description, but here goes nothing.
_______________________________________________
Aza is a girl who hangs with her only friend Vivian, prefers to stay miles away from drama and would rather set herself on fire than than socialize.

Xavier or known as Xavi is a boy who hangs out with his friend Ryder and can charm any girl within a 10 mile radius.

Vivian, Aza's best friend who comes from a very strict background has secrets that he can't share with anyone.

Ryder, Xavi's best friend who has been by his side since forever. He is probably the most loyal and honest person. Or probably the most deceitful thing in the universe.

Brianna schools hard to get 'it' girl. People think that have her all figured out but they are wrong on so many levels.

One of them dies, and now others have to find the reason and the killer behind it.
