KLS posted this on her Facebook page, regarding the Ross books: "Almost all are told from Maggie's point of view, as governess at Collinwood and companion to Elizabeth, who befriends and grows to love Barnabas."
It's been years since I read any of the books but Maggie only makes a brief cameo appearance, in her Eve Arden version, in the first book and is not seen or mentioned again in the series for quite some time. The focal character for the first group of the books is Victoria Winters. Until she simply vanishes without a trace and no one seems to even notice that she's gone. The next book has Maggie Evans as the governess, again with no explanation. Did Paperback Library simply change the name from Victoria Winters to Maggie Evans before the book went to the printer? Maggie is the designated heroine for another chunk of books, until she too disappears with no explanation.
I don't recall any real romance between Barnabas and Maggie or Barnabas and Victoria, for that matter. Vicki had a running romance with Ernest Collins, a cousin that Ross introduced in the first book. Ernest was supposed to have died off page in a plane crash. Similar to Burke Devlin, who was still alive in the books until he too simply stopped appearing.
The only ongoing romantic relationship that Ross seemed invested in was between Barnabas and Carolyn in some of the later books. There was never any hint of that in the series, other than him using Carolyn as a blood source/flunky. But even as a kid, I found the quasi incest angle just yukky.
