Choose the things that fit this particular book best.
Writing about the plot is the trickiest part of a review because you want to give the reader a feel for what the book is about without spoiling the book for future readers. Another possibility is to set up the major conflict in the book and leave it unresolved (Sometimes the waiting is the hardest part or He didn't know what he stood to lose or Finding your purpose in life can be as easy as finding a true friend.) Try to avoid using the tired phrase "This book is about…" Instead, just jump right in (The stuffed rabbit wanted more than anything to live in the big old house with the wild oak trees.) Reviews should answer questions about the characters in fiction books or non-fiction books about people.
The best guide is to focus less on how long to write and more on fulfilling the purpose of the review.
The title of the review should convey your overall impression and not be overly general.
If you retell the entire story, the reader won't feel the need to read it him/herself, and no one appreciates a spoiler (telling the end).
Here are some examples of summaries reviewers from have written: "A new picture book tells a magically simple tale of a lonely boy, a stranded whale and a dad who rises to the occasion." "In this middle-grade novel, a girl finds a way forward after the loss of her mother." "Reared by ghosts, werewolves and other residents of the hillside cemetery he calls home, an orphan named Nobody Owens wonders how he will manage to survive among the living having learned all his lessons from the dead.
In your rating, you should consider how the book compares to other books like it.
Don't compare a long novel to a short poetry book — that's not a valid comparison.
Strong titles include these examples: Although many reviews begin with a short summary of the book (This book is about…), there are other options as well, so feel free to vary the way you begin your reviews.
In an introductory summary, be careful not to tell too much.
