The Thing About Jellyfish and Refugee may be about 2 very different topics, but in many different ways, they’re alike. One major similarity is all of the 4 main characters between the 2 books feel out of place where they are. But, one major difference is one book is set in a war zone, whereas the other mainly stays at a school. Also, a major similarity is all of the main characters are coping with losing someone close to their heart.
