Never in a Million Years

It all started when Adalyn Rose had a little too much to drink and ended up in bed with her best friend's older brother, Ashton Dawson.
They hide it from everyone hoping to forget about it, but when Ashton's psychotic ex-fling, Natalie, intrudes on their vacation, everything changes. Ashton asks Adalyn to be his fake girlfriend for the summer which ultimately leads to some bad decisions.
They both learn a lot from this experience and discover things they didn't know about themselves.
Never in a million years did they think this would happen to them.
What will they do now? How will this go? Where will they end up?
