The Ten Year Affair

Adult • Marriage & Divorce
A Novel
Connection grows at a baby group Lives split into parallel timelines Cora struggles with her marriage Child's fascination with afterlife affects perspective Sam's allure complicates Cora's loyalty

When Cora meets Sam at a baby group in their small town, the chemistry between them is undeniable. Both are young parents who consider themselves happily married, yet their connection grows stronger and the romantic tension between them becomes all-consuming.

Their lives fracture into two parallel timelines: in one they pursue their feelings, in the other they resist. Everyday details of Cora’s life—her depressing marketing job, her daughter’s new fascination with the afterlife, and her husband’s obsession with podcasts about the history of rope—gain fresh perspective as reality and fantasy blur and the novel asks what truly matters.

When Cora and Sam, both happily married young parents in a small town, form an undeniable connection at a baby group, their lives split into parallel timelines.

Reader guide

What to Know Before Reading The Ten Year Affair

A will-they-won't-they romance between two married young parents and the domestic pressures around them. Much of the setup centers on the split into two parallel timelines that explore competing choices. The novel also places attention on everyday family details and a child's fascination with the afterlife. The supernatural or speculative element appears connected to the narrative structure rather than being the main plot driver.
