Even considering KA uses basically a "sci-fi kitchen sink" approach to what can be in these books, it feels pretty safe to say that "possession" or "body co-habitation" was not something most people were expecting

How do you feel about Aldrea passing over two more "likely" candidates and picking Cassie as her host? Do you think it's a good idea for the kids to take off to another part of the galaxy? We're starting to see the Chee cover for them more, which is certainly helpful but also seems to rob them of their own lives in a lot of ways
