I’m very nearly done with ‘The Precipice’ by Ben Bova. Next is either ‘Rock Rats’ in the same series, or I start the Cosmere series by Brandon Sanderson. I’ve read all the Mistborn novels, and they’re fantastic.
Sanderson writes books faster than I can read, so it’s kind of daunting. Ben Bova is already dead, so I don’t have the same problem with him.
