Shadows Alive (Ender's Shadow, #6)

From OSC's website:

For years now OSC has been planning to wrap up the Shadow and Speaker series with a book called Shadows in Flight. Recently, in working on a short novel that follows Bean and his children into space, it became clear that Shadows in Flight was the perfect title for that book, while the big wrap-up novel that brings Bean's children together with Peter and Valentine from Children of the Mind will now be entitled Shadows Alive.

So when you see Shadows in Flight announced as "coming soon," you should be aware that this is a completely different book, a short novel in which Bean and his children encounter an ancient Formic "ark" in space. It's definitely in the main line of the Shadow series, but it is not the end!
