Eerie Efficiency

EERIE EFFICIENCY · FATE HAS QUESTIONABLE TASTE

Dark Romance Trope Randomizer

Spin trope combinations that occur together in published Books, then find matching Books. Catalog-supported combos are labelled when independent verification is not established. Add spice, darkness and obsession preferences—or challenge Eerie with a combo of your own.

How unsuccessful selections are used

If Darkness DNA or the Trope Randomizer finds no book matches, we temporarily store the selections used, matching explanation and related adjustment outcomes to improve discovery. These administrator-only diagnostic reports are separate from general analytics and expire after 90 days. They contain no names, email addresses, account IDs, IP addresses or browser fingerprints. A random attempt code connects retries and adjustments. If administrator notifications are enabled, a copy goes to the configured administrator inbox; emailed copies must be deleted separately. Your saved profile and hard exclusions are not changed.

Loading the trope wheel…

Your Random Trope Combo

Your next fictional obsession starts with a spin.

Tap a trope to lock it. Locks apply when rerolling the others.

Challenge Eerie — choose your own combo

Pick one to five tropes. Every selected trope must match; incompatibility rules still apply. You can stump Eerie: manual challenges may have no verified full match.

Optional intensity

Any leaves that rating unrestricted. Minimum filters allow the same margin below your minimum and all higher ratings.

* Eerie ratings are subjective. Exact numerical matches allow two points above or below your selected ratings or ranges, or one point for spice, within each scale. Your other preferences, exclusions, and required endings still apply.

Optional reader preferences
Anything you absolutely do NOT want?

Books with confirmed YES or UNKNOWN status for a selected exclusion are omitted. Only confirmed NO passes that exclusion. Required endings still need confirmation.

Make your friends choose

Shared links contain only your tropes. Intensity preferences and hard limits stay private. For Instagram or TikTok, download the card and paste your copied caption.
