Writing reviews authors (and Amazon) love ✨

For a brand-new book, a few honest sentences from a real reader genuinely decide its fate. Here's how to make yours count — for the author, for the next reader, and for Amazon's picky robots.

🎯 What makes a review land

Specifics beat superlatives

“Good book, I liked it” helps no one. What stayed with you? What surprised you? What would you tell a friend who asked about it? One concrete moment is worth ten “amazing”s.

Write in first person, in your voice

Lead with your experience — “I couldn’t put down…”, “What got me was…” — rather than a plot summary that starts “This book is about…”. Readers trust a person, not a synopsis.

Say who it's for

“If you liked X, this will land for you” or “best for readers who enjoy a slow burn” is often the most useful sentence in a whole review.

At least 40 words

That’s our minimum — several sentences that explain your experience in a meaningful way. Most good reviews clear it without trying.

⚖️ Honest — in both directions

Mixed feelings are valuable. A review that names both what worked and what didn’t is more believable — and more helpful — than unbroken praise. Nothing here depends on how many stars you give: not this book, not the next one. Honest reviews are always welcome here.

And if a book really missed for you

You always have two equally good options: post your honest review anyway, or send the author your notes privately instead. They read every word, and for a book still finding its feet, that’s often the most useful gift a reader can give.

📝 Keep it plain on Amazon

  • Plain text, normal punctuation — no markdown, asterisks, or emoji in the Amazon review itself (they display inconsistently and can trip the filters).
  • Keep it about the book. Mentions of price, sellers, packaging, other reviews, or links tend to get a review removed.
  • Warn before spoilers, or better, talk about how the book felt rather than what happens.
  • Include your free-copy line — “I received a free copy of this book.” Disclosed is welcome; hidden is removed.

🚫 What we can't accept

At least 40 words, in your own voice. We don’t accept AI-written, plagiarized, generic, inaccurate, defamatory, or discriminatory reviews — honest opinions, good and bad, are always welcome. Amazon has the same allergies, so a review that passes here is a review that survives there.

💡 Small habits that help

  • Jot a note or two while you read — a line you loved, a moment that surprised you.
  • Write soon after finishing, while the impressions are fresh and yours.
  • Don’t read other reviews first; echoes creep in without you noticing.
  • Read it back once before you submit — you’re writing for the next reader.
