Jessica Grant's book Come, Thou Tortoise is a debut novel, featuring a 300-year-old tortoise named Winnifred. The main character is Audrey, and her point of view is only slightly less strange than the tortoise's. Grant talks with Shelagh about why she likes inhabiting the point of view of odd characters.

Also on the show, Norman Doidge talks about life since his mega-selling book The Brain That Changes Itself hit the shelves and changed how people talk about the brain.
