Apparently there's a very obscure Umineko light novel. I found little information about it online, but it's supposedly some sort of adaptation of the visual novel. I couldn't find a scan, let alone a translation, but I did find the covers and illustrations. Each episode is divided in two volumes, but strangely enough, the final episode only has one volume (and yes the light novel is finished). My best guess is that it might have to do with the interactive aspects of that episode, which might've been completely removed alongside with whatever accompanied them. Anyway, does anyone here know anything more about the Umineko light novel?
