Free to Fall

I usually don't read dystopian type novels but this one worked for me (for the most part). It felt plausible for most of the book, but got kind of weird towards the end with the Spoilernanobots in flu vaccines + phones to control people... and deux ex machina of the solar flare storm?? deactivating them at the end... but overall enjoyed it. The romance was nice but not too annoying that people who aren't into romance would actually mind it.
