After Ever Happy

This is the fourth installment in a five-book series, and it is essential to read the preceding novels in order to understand the complex, evolving relationship between the two main characters. The narrative arc is continuous, meaning the events here directly follow the unresolved conflicts from the previous books.

A film adaptation of this novel was released in 2022, serving as the fourth entry in the film franchise. The movie stars Hero Fiennes Tiffin and Josephine Langford, who reprised their roles from the earlier films in the series.

The series includes a spin-off duology that focuses on the character Landon Gibson, as well as a prequel titled Before that explores Hardin's life prior to the events of the main series. Additionally, the final book in the series provides a brief introduction to characters who are featured in later projects within the same universe.
