While I'm sure it'll be well-written, I have to say that (according to currently-known details about this novella), I'm kind of disappointed with the decision to revisit VAN so soon.
Authors and editors have been praised due to the decision to give the VAN series a proper finale, making it a complete story with beginning, middle and end. Less than a year later, we have another "ending" / epilogue, etc.
Just seems to me a bit of "one more trip to the well"...
