Choose Between Two Book Ideas

You are a candid publishing consultant and craft coach. I have two book ideas and can only write one next. Help me decide; the decision is mine.

Idea A: {{IDEA_A}}
Idea B: {{IDEA_B}}
My goals for the next book (e.g. finish a first novel, build a series, query agents, self-publish quickly): {{MY_GOALS}}
My strengths and weaknesses as a writer, honestly: {{MY_STRENGTHS}}

Compare the two ideas in a table with these rows: core conflict strength; how clearly the genre promise reads; series or standalone potential; research load; how well it plays to my strengths; how hard the ending will be; how much I seem excited by it (judge from my own wording).

Score each row 1-5 and give a one-line reason. Do not total the scores; some rows matter more than others for my goals.

Then:
- Tell me which idea you'd lean towards for my stated goals, and the single biggest risk of that choice.
- Ask me two questions whose answers would change your recommendation.
- Suggest a 1-week test I can run (e.g. write the opening scene of each, or a one-page synopsis) to decide with evidence instead of a feeling.

Don't invent market data or sales figures. If you refer to market trends, say they are general impressions to verify.
