I had no idea the books were ghostwritten when I first read the series- I still remember the pang of resentment I felt upon finding that out years later. I basically lost interest in the series after about book 30, though. Everything felt like kind of a slog after that, right up until the end. Also, it felt like Rachel lost her freakin' mind. And her... Rachel-ness. She's got to be a very tough character to portray, Terenia, I totally agree there. She was never really portrayed right after... probably the David trilogy in my mind, even when written by KAA. To me, it kind of feels like book 23 was where the entity known as KAA started to lose interest in this series. Reading them now, there are a few excellent ghostwritten books, but they're too few to alleviate the overall impression. I hate to say it, but I almost wish they'd ended the series quite a bit earlier.
