Terms of Use

Last updated: November 15, 2026

This website is run by the author Sarah Allen. By using it, you agree to these terms.

What this site is

This is an information page about my Fairy Tale Physics books. I don't sell anything here. The buttons take you to Amazon, where any purchase is between you and Amazon under Amazon's own terms.

Content

The text, book covers, and illustrations on this site belong to me or are used with permission. Please don't copy or reuse them without asking. Sharing a link to the page is always welcome.

Accuracy

I try to keep book details accurate, but prices, formats, and availability are set on Amazon and can change. Amazon's listing is the final word.

Other websites

This site links to Amazon and, in the privacy policy, to other companies' pages. I'm not responsible for their content or practices.

No warranty

This site is provided as is. To the extent the law allows, I'm not liable for any loss that comes from using it.

Changes

I may update these terms. The date at the top shows when they last changed.
