There are many pages on the internet which offer advice about how to write reviews.
From my point of view, I try to apply the following guidelines:
2. Try a catchy heading.
3. Think of ways you can hook the reader in – e.g. a quote or comment that links to your readership, or use a question or idea that has come to you from reading the book.
4. Make sure you include details about the title and the author’s name.
5. Find out a bit more about the author, or the inspiration for writing. Are there any any videos about the book, or interviews with the author?
7. Use a question or statement to make the reader think.
