Trying to remember a series of books. First was River of something Light. About a virtual reality world???

The first book in the series was called river of never-ending light or violet light or something like that. It is set in the future and the characters go into a virtual game made for really rich people i read half of them and i would like to read them again but i cant remember the title or the author. They were very large books. I think another of the titles was Throne of %26lt;something%26gt; maybe???Trying to remember a series of books. First was River of something Light. About a virtual reality world???
I think you might be talking about Tad Williams Otherland series.

City of Golden Shadow.

River of Blue Fire

Mountain of Black Glass,



No Throne... but it is set in a virtual reality world run by billionaires and they are big books, which seems to fit most of your description.



Hope this helps.
