Voice can be the most important thing in a written work. Recently, I talked about voice when I reviewed Rick Riordan's Percy Jackson series, and I've postulated before about how important voice is and yet how it cannot be taught (whether it can be learned, however, is a different matter).
One reason why Percy Jackson's voice shines through so well in Rick Riordan's books is because the book is written in a first person point of view. Because of the first person POV, Percy's phrases and attitudes can shine through even in the narrative and description.
However, in a third person POV, especially an omniscient third person POV, it becomes much more difficult to show voice. Voice is limited to dialogue (internal or external) and it becomes tricky trying to put the character voice into the description and narrative without having author intrusion.
So here's my question: What is a good book that shows voice but is told in 3rd period?
