Is there always both an antagonist and protagonist in a story or can there just be a protagonist. The book that I'm talking about is New shoes for Sylvia and I only think there is a protagonist

Yes, there need to be both the protagonist and the antagonist. Otherwise, there wouldn't be much of a story!

The antagonist might, however, not necessarily be a person.

In most traditional stories, you will typically find both an antagonist and a protagonist. The protagonist is usually the main character or the one whose perspective we follow and cheer for. They are often the one who faces challenges and undergoes character development throughout the story.

On the other hand, the antagonist is the opposing force or character who creates obstacles or conflict for the protagonist. They can be a person, a group, or even an internal struggle within the protagonist themselves.

Now, specifically speaking about the book "New Shoes for Sylvia," written by Johanna Hurwitz, it is important to note that not all stories follow a set formula. Some stories may focus solely on the protagonist and their journey without a clear antagonist. However, there may still be other characters or circumstances that present challenges or conflicts for the main character.

To determine whether "New Shoes for Sylvia" has both an antagonist and a protagonist, it would be helpful to consider the plot and the characters' dynamics. Look for significant characters who oppose the main character's goals or create obstacles for them. If there is no clear opposition, it is likely that there is only a protagonist in the story. But remember, every story is unique, and it is ultimately up to your interpretation as a reader.
