What's it like to write a book with your mom, when your mom is Jodi Picoult? That's my first question for Samantha van Leer, who just finished writing the young adult novel "Between the Lines" with her mother - who happens to be Jodi Picoult (it's an unusual way to spend your sophomore and junior years of high school, if nothing else). Ms. van Leer says it was (mostly) fantastic (well, except when it wasn't). Watch the video to see the rapport between Ms. van Leer and her famous mother as they dish on writing a G-rated book, what happens when you mix up the medieval words for "shirt" and "pants," and how much fun it was to create an wholly imaginary, personal world - together.
