You probably didn’t expect the bestselling author of “The Notebook” and the acclaimed director of “The Sixth Sense” to start working together, but you’ll be glad that they did. Nicholas Sparks and M. Night Shyamalan have collaborated on a supernatural love story that’s being released as a novel first, followed by a movie next year. It’s called “Remain” and it follows a grieving architect who moves to Cape Cod and meets a mysterious woman. Nicholas joins Tom Power to talk about the book, his deep love for horror, and how he almost collaborated with Night on the movie adaptation of “The Notebook.”
