Posted by John David Anderson is a fiction book, in the realistic fiction genre. The book is about Frost, the main character, and his group of friends overcoming many challenges. They get a new friend, they almost lose one, and they overcome various amounts of bullying.
Personally, this book was a little confusing to follow because it was a little all over the place. The book kept going into flashbacks and sometimes you couldn't tell that it did that. In the beginning I was very confused but as I went on I got really invested in the story. And I very much liked the outcome of the book and how it resolved the problems. I would definitely recommend this book to 7th and 8th graders. It is definitely written for them, as the setting is also in a middle school. I would rate this book 4 out of 5 because it was originally hard to follow in the beginning but the outcome was very good.
