About the author

Jan Walker checks everything twice.

Jan Walker writes trivia books for people who correct the television. Cars and trucks with real cult followings, plus the family series about the people who taught you everything — whether you asked or not.

No AI-scraped listicles bound into a paperback. Every question is cross-referenced against two independent sources — race records, homologation papers, patent filings, USDA tables — before it earns a page. When estimates disagree, the book says so honestly.

Available worldwide in paperback and Kindle. Follow along on X @JanWalkerBooks and Pinterest.
