I looked up
Speaker for the Dead on Wikipedia, and now I know what
@Allyn Gibson was talking about. Spoilers weren't an issue, given that I have better stuff to read.
I suspect that at least some people here (perhaps not as many as on Fountain Pen Network or PIPORG-L) know that I'm a classical music geek, with subscriptions to a series and a half at Hollywood Bowl (i.e., the entire 10-concert Tuesday Evening series, and the odd half of the Thursday Evening series), and two 4-concert series at Disney Hall (whichever of the two Colburn Celebrity Recital series looks the most interesting to me, and one of the two Chamber Music series). There are only two composers for whom I will do a "subscriber privilege" exchange to avoid: Mahler, because most (but not all; I rather like the "Titan" Symphony) of his stuff bores me, and Wagner, because nothing he wrote is good enough, in my estimation, to make up for his being a Nazi before Hitler was even born (I'm Goyish, and I have Jewish friends who are more forgiving of Wagner).
And then there's The Novel Which I Shall Not Name In Public (because I don't want to be the reason anybody develops sufficient morbid curiosity to buy a copy). I'm constitutionally incapable of book-burning, but I have considered sealing it into a stud cavity of a building. The only favorable thing I can say about it is that it proves that a truly self-published opus, that isn't weighed down by any known vanity imprint,
can make it into the brick-and-mortar bookstores, even if it's pure equine scat. In other words, there may be hope for my own unpublished opus yet, because it
isn't equine scat, or any other kind of scat.
But they are the exception, not the rule. In general, I
can forgive an author (or a composer, or any other artist) quite a bit. Now that I've finally gotten around to reading the Harry Potter series, I'm buying British editions to avoid U.S. editorial changes, and I'm buying them on the used market to avoid adding directly to JKR's royalty revenues, but I'm still buying and reading them, one by one. But in the case of the Ender series, neither the author nor the subject matter hold any appeal for me. Not when I have ADF's entire HC milieu (to date) occupying a dedicated shelf in my library, and I've got all the ST novels of CLB, GC, DM, DW, DD, JK, JMF, JS, and UMcC (although she did have that one opus I don't think I'll be re-reading any time before heat-death of the universe, because of the subject matter) to choose from.
(And just because Barbara Hambly inflicted drochs upon SW readers doesn't mean I don't absolutely adore her ST/HCTB unauthorized crossover,
Ishmael.)
