The Lightest Object in the Universe by Kimi Eisele
Loved this post apocalyptic love story! The Road meets Station Eleven with it's own hopeful flare. The world of electronics, the internet and cars as we know it has ended but life hasn't ended for our protagonists. Beatrix is determined to build a better community through a bike brigade, radio drama and self sufficiency. Meanwhile Carson has set out on a walk across the country to get to Beatrix even though he has no way of contacting her or knowing if she is still there. Both of their journeys take them to unexpected places and change them forever.
