After We Fell ended with Hardin reeling from a hard truth about his real father, and After Ever Happy opens in the wreckage. His drinking and temper spiral as he tries to process it, and Tessa — worn down from propping him up while her own life comes apart — finally tells him she needs distance.
What follows is a harder, slower chapter for both of them: Tessa rebuilding herself away from the relationship, Hardin in therapy and confronting his family history, each learning separately what the other couldn't teach them. Fourth in Anna Todd's After series, After Ever Happy asks whether Tessa and Hardin can find their way back to each other once the crisis has passed.
