Query: Sub Par Silverberg, only for die-hard fans of Silverberg

I love Silverberg, he's become my favorite sci fi author by far. With that said, this book is as close to garbage Silverberg will get. What a slog just to get through it. The book should have been edited to less than 100 pages because nothing really ever happens, a whiny, flawed, racist, ex-king/future king recants old stories from his youth amidst a swirling future backdrop that is poorly built except for small snatches. Only a few worlds and technologies and cultural ideas get elaborated upon. And I found the ghosting done only by gypsies into the past and present and future to be fairly stupid and ill-conceived. Some parts were interesting but most of time I found myself saying...I think I care, I think I care, I think I care, I think I don't.
