When the author of a series dies before finishing...

So I'm a big fan of paranormal and gothic romance and general fiction, and there's a series by a woman named L.A. Banks that I really loved, about a vampire huntress called a Neteru and how she and her crew end up kicking off the Apocalypse after a few years of fighting the forces of evil. It was a really good series that I enjoyed, and I thought it was more or less ended, but come to find out she had started another series with the children of that squad and how they were going to find their destiny fighting against the Antichrist in the aftermath of the Armageddon, so I was naturally enthused. Only thing was... even though the first book in that series was released in 2010, and it said the second one was coming in 2011, I couldn't find it in the Nook store.



So I took to the internet, and lo and behold I find out that this poor woman died in 2011 of adrenal cancer, leaving that series and a couple of others she wrote unfinished. I'm somewhat torn about this as a result; I would really, REALLY like to know how she would have finished it, but by the same token when someone ghost writes under someone else's name (like. V.C. Andrews for instance) the resulting work just isn't the same somehow, and you typically end up vaguely disappointed with the resulting book. I'm curious to know whether anyone else has ever faced this issue with a series or author they genuinely loved and what they thought of the whole thing?
