I loooovveeeed Station Eleven it's one of my favourite post apocalyptic books. You have excellent taste!
I'm reading the Willow Falls trilogy atm. It's post apocalyptic and has some weeved narratives. It's on kindle unlimited and I'm absolutely gripped by them, best books I've read in years.
Other post apocalyptic book that's excellent is Lockdown the first couple are great. Sadly they go off the rails.
Oh and if you haven't already read it then Day of the Triffids is a classic and excellent.
