The Giant's House by Elizabeth McCracken is narrated by the character Peggy Cort. She is a young librarian who lives near Cape Cod in the early 1950s. The short book is about her falling in love with James Sweat, a boy who suffers from gigantism.
The story is told from the first person point of view, which is indicated by the use of the first person singular pronoun "I." A first person point of view limits the narration in some ways. Often, an author will choose to use the third person omniscient point of view, because it gives him or her the ability to narrate the thoughts of multiple characters much more easily. With first person the narration can't do that as well. What first person does do really well though is allow the reader to get to know the first person narrative main character extremely well. The reader sees what he/she sees, hears it as they hear it, and is allowed into that person's thought processes.
