Meet Nora Byrne. Over-thinker, under-achiever, champion vibes-killer. 

After spectacularly blowing up her life, twenty-one-year-old Nora Byrne retreats to the family home with little to show for herself but a shiny new autism diagnosis. 

But it's hard to process this news under the critical eye of her mother, who already treats her like the black sheep, and the rest of her less-than-understanding family. 

Worst of all, it's the week before Christmas, which means mandatory socialising with the neighbours - including Fran, her childhood best friend, last seen when she broke his heart (again).
