How to Write a Synopsis for a Novel With Two Timelines

A two-timeline synopsis has to reveal the whole plot, including the ending. It is not jacket copy. Its job is to show how the past and present stories affect each other without making an agent solve a chronological puzzle.

Choose a clear spine

Start with the present protagonist's goal and the past event that puts it under pressure. Label time shifts consistently. Follow cause and effect: what the earlier character did, what the present character discovers, and how that changes the next action.

Do not alternate mechanically

The synopsis does not need a paragraph for every chapter. Group related developments so a reader can understand each timeline. Switch when information from one changes the meaning of the other.

Reveal the connection

Do not write 'a shocking secret links the women' and stop. Name the secret and its consequence. An agent uses the synopsis to evaluate structure and payoff, so hiding the twist defeats its purpose.

Keep the cast small

Introduce only people necessary to understand major choices. Use relationships and roles to orient the reader. If three characters share similar names or functions, the synopsis may also expose a clarity problem in the manuscript.

Connect the timelines through cause and revelation

Imagine a present-day daughter investigating a sale of the family house, while the past timeline follows her mother hiding a letter. A mechanical synopsis alternates every chapter and forces the reader to remember two sequences. A clearer synopsis can summarize the mother's concealment, then explain how the daughter discovers its consequence.

Keep the important revelations even if you reorganize their presentation. The synopsis should tell an agent what the secret is, who acted, and how the discovery changes the ending. Do not use 'a shocking truth emerges' where the actual truth belongs.

Write a one-paragraph summary of each timeline separately, then a paragraph explaining their connection. Use those three paragraphs to find the simplest order for the complete synopsis. Include dates or ages only where they prevent confusion. The goal is to demonstrate a coherent novel, not to reproduce the exact suspense of reading it.

A practical revision check

Can someone explain both timelines after one read? Is the connection explicit? Are the final choices and ending present? Did I follow the recipient's requested length and format?
