Book 4?

For those who have asked about a book four in the River Wolf Pack series, I'm sure you noticed that book 3 left things open. I am tentatively planning a book four, because there's still more to explore. I'm thinking about writing it from the following points of view: River's, Brooks', Foster's, and either Milo's or Justin's. If you have a preference for that last one, please leave it in the comments below.
