I forgot I had a Fandom account.
So, I expect some of my predictions to be inevitably accurate, like Croaker now remembering his time in Port of Shadows hence the title of this book. My guess is that Lady's going to become obsessive about bringing Booboo back to good health somehow, Croaker might say out loud at some point, "My wife is a Pitiless Rain." Really just referencing her once being Mischevious Rain but Arkana and Shukrat would take it as a new name for Lady.
But I will not be able to create content on par with what I expect from Glen Cook. I planned on making up a lot of my own content to add onto what I feel are possible or even inevitable things (like the above about Lady). We might even get to see Khatovar in this next book! I was going to try and come up with a Khatovar of my own, thinking Cook ended Soldier's Live with Khatovar as an open ended thread for us all to imagine what it might be. Since we're getting a real sequel I think I will save my creative juices for writing something set after even that, or as an alternate fan-finale.
