Happy Hour

This is not a novel, it's a diary of a tweenager. An absolutely obnoxious, self-important snob of a tweenager, who according to herself is absolutely amazing and capable and just simply the best, yet is struggling to make ends meet and has no visible ambition in life. She's not even fun or good company.
I kept reading because for a while it seemed the friendship between the two main characters was somewhat redeeming. But then even that turned sour and it transpired that our MC clearly hates her bestie.
I only finished the thing so I could sit and seethe a little longer.

Painful, ego-upping venture this.
