I know that Vlad's series is not done and you can say much but I just wanted to put it out there... I'd love to see Maximus get is own book if you continue to write within the Night Huntress World series?
I really like Maximus as a character and I do have ideas for a story centering around him, but he'd be waiting in line behind (potentially) an Ian story and then possibly a Katie-centered story. To clarify: Ian and Katie, if they get stories, would have separate ones. I am NOT matching them together as a couple, even if it was set in the future when Katie would be older. So, it's a "maybe" on a Maximus story :).
