What are the physical appearances of Daniel and Erika in Daniel's Story by Carol Matas?
In Daniel's Story the descriptions are not elaborate nor are they joined to the introduction of a character. The descriptions are more psychological than physical. However, Daniel does briefly describe himself in Chapter 1 by describing some old pictures. When he was six, he had "pudgy cheeks," which means that as he has grown older, he will have a well-built physique, not a slight one nor a rotund one. He also describes his "thick black wavy hair," which will not have changes over time as sometimes will happen with blonds whose hair may darken.
In the same section he describes his sister Erika as being two years younger and slightly introspective as well as musically inclined. She is introspective because while on the train ride to some unknown infamy, she sits humming a tune. Daniel associates her humming with a new composition she is mentally developing for her violin. To find the descriptions of the other main characters, look for brief remarks and for tell-tale passages, like this one about Erika, that give psychological information.
