Having read both, it is set in the same universe. It features a side character from the main series, but nothing that I'd consider a major spoiler for any of them.I've started to read The Imposters in paperback. (Sorry, but I've been busy with other things and distractions so I have barely touched it yet, not because it wasn't interesting.) I thought it was a stand alone, but is it set in the same universe as Captain Smith? Or, is that something I have to work out as part of the puzzle of the story? Or, is it a different kind of Ghast Empire?
