here's some tricks. write on a book that you have read and really enjoyed. first, start by writing down basic event in the book. have your first paragraph be an intro explaining like the author, the reason the book was written if known, and other backround info like that. paragraph two explain what happens in the first few chapters and the signifigance it had. then for paragraph 3, do the same thing but for the middle. i'm pretty sure you get the point for paragraph 4. just rap things up and explain the call to action. for the final paragragh (paragraph 5) , explain your views on the book, the message, ect. tip: something that might is to go onto cliff notes or something and read the anaylisis of each chapter.
