Codi and Hallie are two sisters who are very much alike, but at the same time have differences in personality that make them unique too. For instance a similarity between the two sisters would be their intelligence. Codi is very smart seeing as how she went to medical school and almost became a docter. Hallie is intelligent in the way that she is dedicated to her love of gardening and plants, and knowing what is happening around her. Both girls are also very humane and sympathetic. When they were younger they tried to save coyote pups, and now in the present time Hallie is out helping in Nicaragua and Codi is being there for her father while he suffers from alzheimers. Codi also cares about animals, as showed when she thought the kids were beating up a peacock. Not only are they alike in these ways but they also are alike in their physical appearance. Hallie and Codi are very tall, and look alike. The last word i would use to describe both of them is adventurous. Hallie travels to Nicaragua and takes her time sightseeing along the way, and Codi can never settle into one place. She has been all over the world and is always planning on leaving to go somewhere else. There are also some things about each Sister that makes them different from each other. Codi is lost and doesn't feel like she fits in anywhere and is self concious, where as Hallie can feel at home anywhere she goes, and is genuinely happy with who she is. Codi and Hallie are both very interesting and developed characters who I am eager to read about and see what happens in the final part of the book.
