So much of avoiding writing a review for someone’s book is the idea that you can’t write.
P-shaw…

It’s easy. It takes five minutes. And it is the single most effective way to support the author of a book you took the time to read. (Or maybe even didn’t finish…) Here’s the 2 – Yes, 2! – Steps to Writing a Review
First,
And Second,
Write a review. Not a report. Not an essay. Just tell them what you think about their book.

Use the 3-Word-Rule.
“I loved it.” Or, “I hated it.” Or just the first three words that come to mind: “funny, sad, wow.“
If you’re game, you could elaborate by answering why?
Why you loved it – I felt every word of this book, I’ve been there myself.
Why you hated it – I cried the whole time. Ugh.
Why someone else should read it – I want my mother/brother/husband/daughter to read it because they’ll understand me better.
That’s it! Quick, easy, painless, and a boon for an author who’s trying to change the world!
With Overwhelming Gratitude,
Alex.
