As for if it was a good book or if its worth your time. Its hard for me to be objective. I don’t feel that Mockingjay can be summed up with so staments on the flow of the plot or if it kept you interested or a letter grade or stars. I think if Suzanne Collins had been ubducted by the most illeterate aliens and wrote the book I would still need to read it till the end.
So whether you decide to read the book is up to you. But I'll leave you with this... Did I enjoy the book? Yes. Did it fufill your expectations? It exceeded them. Did you find it hard or easy to get through? A fair balence of both. Would you read it again? Not for a long time.
