Writes a complete holiday cozy mystery — the one book idea with a built-in annual season.

The holiday shelf is the most reliable seasonal buy in fiction, and it is bought in December by people who wrote it in July. Your list can still make this year’s.

Holiday Cozy Mystery Novel Maker takes their idea to a finished, publish-ready novel — Hallmark-warm, clean, and fair. It builds the case backward from the solution and lays every clue on a ledger — then code checks that ledger for fair-play breaches and shows your subscriber each one it finds. One chapter, then it stops and waits.

The proof is full length: the same engine wrote Calder Bay, an 82,578-word police procedural, end to end, with 0 timeline contradictions across the whole book.

$27 front end, four one-time upgrades, no downsells, $505 full stack. Launching Nov 17 — in time for the December buy.
