What is it about dark matter and what is it actually?

Lisa Randall will explain here to talk about her new book, Dark Matter and the Dinosaurs.

What it's called dark matter rather than ordinary matter is that it doesn't interact with light.

That is to say, light goes right through it.

How do you escape North Korea and what's it like afterward on the outside?

Louisa Lim will be here to talk about five new memoirs by people who have fled North Korea's

communist dictatorship.

The other things that we learn about North Korea that are really alarming is the precariousness

of life and really the weakness of family ties.

How easy it seems to be for people to be so desperate there that they will sacrifice,

Alexander Altair will give us an update from the literary world.

And John Williams has bestseller news.

This is Inside the New York Times Book Review.
