When I write the dust jacket blurb for Gruefield, it will go here. The draft has been completed. Why the odd title? It's derived from something in Shadowboy, so you'll have to read that to understand the reference. It's not obscure or easy to overlook, but it is a bit spoilery if I tell you what the title is talking about.
For the time being, all I should say is that Gruefield is the sequel to Shadowboy. It takes place a year after the start of Shadowboy, and involves much of the same cast.
There are short stories and a novella set into the gap which do not involve the primary cast as their main characters, but they don't have pages yet. Their anthology will be titled "Lucid Blue (And Other Tales Too)".
