I recommend these two books to new writers.
- Elements of Style - It's an old book of about 100 pages. You can read it in 2 days if you're serious. Must read!
Nicely Said: Writing for the Web with Style and Purpose
“Nicely Said is the best book I’ve read on the art and craft of writing. It’s clear, concise, timely, and compelling—in other words, exactly the kind of content the authors teach you to create.”
—Kristina Halvorson, coauthor of Content Strategy for the Web
You can find these books online if you search well like a Ninja 😉
