The Prompt
When marine biologist Seren takes a research posting at a remote lighthouse on the Welsh coast, she expects solitude, seabirds, and silence. What she doesn't expect is to find a box of unsent letters hidden in the lighthouse walls — love letters written by the previous keeper to someone named only 'M.' The letters span thirty years and tell the story of a love that survived distance, war, and the keeper's own stubborn pride, yet was never spoken aloud. As Seren reads them, she begins corresponding with the lighthouse's supply boat captain, Jamie, who delivers provisions every two weeks. Their practical messages about weather forecasts and grocery lists slowly transform into something deeper. But Seren is here for one season only, and Jamie is rooted to this coast like the cliffs themselves. The letters in the wall warn her: some loves are meant to be lived, not preserved in secret.
Variations
- 1. The letters aren't old — they're being written now, by someone else living in the lighthouse's second cottage that Seren didn't know existed.
- 2. Jamie is the grandchild of the mysterious 'M' and has been searching for these letters for years.
- 3. Seren discovers that the lighthouse keeper who wrote the letters is still alive — in a care home in the nearest village — and the love story isn't over yet.

Frequently Asked Questions
- What romance tropes does this prompt use?
- Slow burn, forced proximity (lighthouse isolation), epistolary elements (letters), and a parallel love story (past/present). These tropes create natural tension and emotional depth.
- Does the romance need to be the central plot?
- Yes — in romance, the love story is the main arc. Seren's research and the historical letters should serve the romantic tension, not overshadow it.
- Can I write this as LGBTQ+ romance?
- Absolutely. The prompt uses gender-neutral framing for 'M' deliberately. Any combination of identities enriches the story.
