Alone (Sequel to Diana)

Sequel to my first book Diana.

Liam and Diana have been married for almost a whole year. Everything was perfect.
But suddenly things take a turn for the worst with Serenity.
She hangs out with some troublemakers from school and they screw up everything she had going for her, like college and her own family.
Serenity and Diana grow distant and barely talk. Diana watches her daughter suffer from all of this and blames herself for never telling Serenity that stuff was bad.
Will Diana go back to her old ways, even if she is a 19 year old mother of 3 kids?
Will they get Serenity back on track or is she already to far gone?
