Try these two styles of book reporting for 5-8th graders. My class loved them.
Students bring a grocery bag and write the title and author in marker clearly on the outside.
They then select 5 items from home to put into the bag they relate to their story. As they explain the items, they are telling sections of the story, but not the whole story. As they explain the scenes, they are telling parts of the story. The fun part is bringing something to eat that in someway relates to the book. We had good eats with our milk time and munched while listening to oral book reports.
