Comparing publication of two books by dead authors: the last Discworld
book written by Terry Pratchett, and a Lisbeth Salander book
written
by someone other than Stieg Larsson.
I urge you to resist the marketing hype associated with these books.
You might want to get them, but hype should not be rewarded.
I am mostly not a fan of Pratchett. I thought Small Gods was very
good, but the other few Pratchett books I've read did not especially
impress me. However, I am impressed by the stance of Pratchett's
daughter towards honoring his memory.
By contrast, Stieg Larsson's family seems to be behaving in a sleazy
manner. It seems that his mate really loved him but his relatives
love his money-making potential more.
This illustrates the important difference between works of practical
use, such as software, and works of art. It is a very good thing that
others now continue the development of the GNU programs that I
initially wrote. Their work is useful; they add features and fix
problems. Whether their style is similar to mine is hardly worth
thinking about.
But it is foolish to hope that someone else, even someone talented and
skilled, can continue the work of a dead author of fiction.
