The creation of Jenna Lamia, Netflix’s ‘The Perfect Couple,’ is based on the eponymous 2018 novel written by Elin Hilderbrand. The crime drama series follows a young woman named Amelia Sacks, who is about to get married to the man of her dreams. The groom happens to belong to one of Nantucket’s wealthiest families — the Winbury family. The wedding is the talk of the town, as everyone involved and uninvolved is looking forward to the event.
