The Giver
I recommend you should read the Giver because you get every detail about what happens, stay interested, and you can't wait to find out the ending. First, you will get to know the memories Jonas receives that aren't shown in the movie. Next, readers will know that all the kids ages are a lot younger in the book, which keeps the story interesting. Finally, when Jonas suggests the idea of going Elsewhere, the readers were intrigued and they wonder what Jonas would do. In conclusion, if you read the book you will understand what happens instead of being confused about the movie.
