I finished The Plague by Camus the other day. I found it quite hard to get into, I much preferred The Stranger. Having said that it could be because I've been up to my eyeballs in painkillers recently.
I've just started on Annhilation by Jeff VanderMeer, based on a recommendation by a friend. About 60 pages in and enjoying it so far.
Seems similar to a less spooky version of Roadside Picnic by the Sturgatsky brothers.
