Decisions

1 · Kindle+ and KDP Select

Enroll all three ebooks for one 90-day test term

Amazon brings 68% of ebook sales. Kindle Unlimited is now Kindle+, and audiobook listening there is paid from the same KDP Select fund as page reads.

Trade-off: the ebooks must leave Apple and Kobo for 90 days (paperbacks stay wide), and a title can't leave mid-term. Amazon hasn't published per-format rates yet, so turn auto-renew off and judge on real numbers at day 60.

2 · Virtual Voice audiobooks

Books 1–2 ready; fix Book 3's table of contents first

Virtual Voice is a free, invite-only beta for US-distributed ebooks, and it needs a linked table of contents. Once a book is in KDP Select, its Virtual Voice edition joins Kindle+ automatically.

Check each book on the Bookshelf for the "Add Audible audiobook with virtual voice" option. If it isn't offered yet, nothing is lost by waiting.

3 · Kindle Translate

Translate Book 1 into German, as a single test

Germany is this series' biggest market outside the US at 9% of Amazon sales. Kindle Translate is free, covers German, and translated titles can join Kindle+.

Preview the translation before it publishes rather than letting it go live automatically. Hold Books 2–3 until German readers move on from Book 1.

4 · Audible deadline, Dec 31, 2026

No action needed

The legacy Audible royalty model ends December 31, 2026, but this series has no ACX titles. Any audiobook made later enters the new model automatically.

5 · AI disclosure

Nothing to declare now; declare the German edition

KDP asks about AI-generated text, images and translations separately. The current books need no disclosure. A Kindle Translate edition is an AI-generated translation, so answer yes to the translation question for that title only.

Book 1 listing: Tea and Trouble

New description, keyword slots and categories, ready to paste into KDP.

When Nell Penrose finds the harbourmaster slumped over a plate of untouched scones in her brand-new tea room, she has two problems: a closed shop and a village that thinks she did it.

Nell moved to Trevossa Cove for a quiet life by the sea. Instead she's juggling suspicious regulars, a cat with a talent for stealing evidence, and a detective inspector who'd rather she stuck to baking.

To save her tea room, Nell has to find out who wanted the harbourmaster gone before the tide turns again.
