I've been listening to them and yes, they are interesting. You also might get a little hint on what will or will not happen. I try to avoid outright spoilers. I did read a major female character would be killed, but didn't know which one. I figured it wouldn't be Kate, Sun or AL, so that left Shannon and Claire. On the podcast before Adandoned they read a question from a fan asking about having more of Charlie's story. The answer was that there will be much more on Charlie, Claire and their relationship. So that told me Claire wasn't going anywhere and it had to be Shannon.
