Having just finished re-reading Splinter, I’m going to have to strike it from my personal canon. It doesn’t fit into a post-ESB world.
I’m planning to re-read the Solo trilogy next, though, to see whether it or the film wins out.
I’m still bitter the novelization of Solo wasn’t released closer to the film’s debut, as I had hoped to read that first, able to just picture Harrison Ford in my mind’s eye and pretend it’s any old EU novel before seeing the movie.
