Besides carefully choosing and reading some books published during 2021 so I can complain how the old stuff is better (*cough*), my main goal is to read/finish some of the chunky anthologies/collections/omnibuses I've accreted over the last few years. Right now I'm not quite half-way through The Man from the Diogenes Club by Kim Newman, better than a third through Two-Handed Engine by Henry Kuttner and C.L. Moore, have two more novels in a P.D. James omnibus and three in an Eric Ambler. Not sure I'll get to all of those or whether I'll peal off to something else -- I have the collected stories of C. J. Cherryh and three or four anthologies by the Vandeermeers, at least one chunky Ellen Datlow anthology ...
I also hope to get to The Thirteenth Tale by Diane Setterfield, The Shadow of the Wind by Carlos Zafron, and "[a]fter that, I hope to read a short collection by Virginia Woolf, at least one novel by Dawn Powell, a couple of novels by Dorothy B. Hughes. I also hope to get to A Connecticut Yankee in King Arthur's Court (Twain) and Travels with Charley (Steinbeck), and reread Chronicle of a Death Foretold (Garcia Marquez)," which is what I said last year.
But as others have mentioned, nice new shiny objects will probably appear and deflect me from my current plan.
