Hello, I read 2 books in the 1980's and I can't recall the titles or the authors. Book 1 involved a being/entity that had evolved and existed inside of a star. That being was named something like, "Wan-to" or "Wan-Tu". WT was able to and did create replicas of itself and those replicas would live in other stars. WT and the replicas were able to manipulate stars, matter and energy to cause supernovas and ETC. Later in the story WT was fighting against the first replica #1 as each became paranoid and wanted to destroy the other. WT created several ability limited replicas of itself to bait out replica #1's location star. The final replica was given an assignment to live in the earth's sun and cause the sun and several stars to begin to move through space at a speed approaching relativistic speed. This movement of the sun caused replica #1 to reveal itself and WT destroyed replica #1. Does anybody know the book title and author?
