Were Exile's Song, The Shadow Matrix, and Traitor's Sun written by Marion Zimmer Bradley alone? I do not see that they are published with a co-author mentioned.
Rediscovery was previously co-authored, and Mercedes Lackey is credited.
All the books after the three I am asking about, are co-authored with Deborah J. Ross, and published after Marion's death.
Exile's Song, The Shadow Matrix, and Traitor's Sun were published toward the end of Marion's life; I do not believe she was in very good health at the time.
Also, the style of the writing is extremely different from her other novels, the characterization is different, and some of the preexisting characters seem to have developed different personalities than they had in the previous books. This has made me curious.
