Why this must be read:
This is really long Empires non-band AU, Tom Conrad/Sean Van Vleet as the main pairing. It's a great read for those who just like a good slash romance, no need for knowledge of any bands. You'll appreciate the characterization if you're familiar with Bandom, but it's not essential for enjoyment. I liked the feeling of friendship among all the characters in this story.
Empires primer here for those who need more information or context. And here's a Tomrad history, if you want to know more about Tom and his buddies Jon and Nick.
