Three years since the sudden death of her beloved husband Etienne Grenaud, and the end of her life in the beautiful French village of Monpazier, 30-year-old Ava is at a loose end. Now back in London, she spends most of her time with her semi-regular hookup Archie and working on the unfinished draft of her book: The Grief Diary. But when her editor tells her to head back to Monpazier to focus on finishing the book, Ava finds herself learning how to navigate life back in the small town without Etienne.

Ava struggles to come to terms with her feelings towards the town, especially after the arrival of Etienne's estranged brother, Florian, which digs up resentment from the past. But with the support of new friends, including her octogenarian landlady, Ava rediscovers the person she was before her husband, and finds out what her life could look like, After Ever After.
