Sonar, You're My First Novel

Sonar: I had this story kind of in the back of my head after hearing so many cases. And for the longest time, I just didn't know what to do with that story because it didn't fit into my true crime world. So finally, I decided, you know, if this is going to be anything, I think it's big enough that it could be a book. It was a number one New York Times bestseller. That's fantastic. Do you think you're going to write more of them? I really want to do another novel like all good people here. Also wants to do something more young adult, like a modern day Nancy Drew.
