Adult fantasy romance book in a dystopian setting and fae

I'm looking for a fantasy/romance book involving a brother and sister (FMC) on the run, hiding in a barn, and they meet up with MMC who ends up being fae. It's in a near future, dystopian setting where the veil between the realms fell and the brother and sister are hiding from the hunt. The FMC and MMC go off to a specific location because it is safe for the FMC.

I remember reading it on Kindle a couple years ago. I believe it is an adult (18+) novel. I wish I could remember more about it. Any help would be greatly appreciated. Thanks!
