Onyx storm worth finishing??

I’m almost half way through onyx storm and it’s honestly so bad. I don’t remember the first book being this terrible? The dialogue is just so cringe, too much swearing (I’m not offended it just comes across as lazy to me), sex scenes are cringe, half the time nothing is happening & I’m rolling my eyes at every page, it’s just dragging on!! Do I keep reading (kinda mad I spent $18 on a kindle book😵‍💫) or should I just look up all the spoilers lol
