Trinnie is due to celebrate her thirtieth birthday in March of 2020 which is an important milestone for her. Over the last five years Trinnie has made some close friends, all seven of whom are invited to the party. She chooses where to go and has one of the friends make all the arrangements at some of her favorite hangout spots.
Then Covid hits, everything has to be cancelled and the birthday celebration becomes a Zoom party. Amy, who is making the arrangements, decides to throw a creative wrinkle into things (unbeknownst to Trinnie) by asking each friend to create a T-shirt which visually explains their relationship to Trinnie. They will then reveal their designs at the party through an unboxing. Each chapter begins with a party goer unboxing their T-shirt revealing their connection with Trinnie. As the party begins all of the guests realize that other than Trinnie, they are looking at six strangers.
Though the story is set in Seattle the reader is transported to other parts of America and to Europe through each character's relationship with Trinnie. Each party guest describes their personal journey in becoming friends with Trinnie and the impact she's had on their life. Each individual history has twists and turns which shine light on who these friends are as well as giving the reader insight into Trinnie's inner thoughts.
