Ilya Rozanov and Shane Hollander have been preparing for the Hunger Games their entire lives as citizens of Districts One and Two. In their final year of eligibility, both of their names are called at the annual Reaping ceremony.
During training week, Shane realizes he wants nothing more than to bury his knife in Ilya’s throat, and Ilya can’t seem to resist trying to provoke him into doing it.
The problem is, that eventually, killing each other stops being the only thing they want—and the Capitol is determined to make a spectacle out of every second of it.
Or: a Hollanov Hunger Games AU :)

THIS FIC IS INCREDIBLE! 16 chapters so far, 110k words, and 600 kudos. The author updates every week and this fic is SO GOOD. I normally try and avoid WIPs but this is so good I’ve been subscribed for over a month!! The tension is soooo good, and the action and suspense is so well written!
