All Your Perfects by Colleen Hoover

This novel is a raw and emotional exploration of a troubled marriage, asking whether a love with a perfect beginning can survive the imperfections of real life . The story unfolds through a dual timeline, alternating between "then" and "now" .

In the "then" chapters, readers witness the whirlwind, fated romance between Quinn and Graham, who meet under disastrous circumstances—discovering their respective partners are cheating on them with each other . Their connection is immediate and intense, leading to a seemingly perfect marriage .

The "now" chapters reveal the present day, seven years later, where their marriage is crumbling under the immense, silent strain of infertility . The joy has been drained from their relationship, intimacy has become a painful chore tied to ovulation schedules, and communication has broken down into secrets and lies . As they withdraw from each other, a forgotten promise from their wedding night—symbolized by a locked box containing love letters, meant to be opened only in a moment of crisis—becomes their last hope to save what's left of their marriage .
