A Shift in Fate

Revenge always has a cost. Mine was a secret.
Everyone knows about the devourers. The wicked monsters that threatened to destroy all the realms until the fae and daemons locked them away. Slight problem. I have devourer magic.
It's only a matter of time before the fae or daemons learn about my abilities. Best case, they bind me to them in service. Worst case... a very excruciating death. I'd prefer neither, which means I need to make some powerful alliances fast.
Enter my best friend, who happens to be a high-ranking daemon, with an offer. Go to the fae realms. Find the mysterious kid who is running around with strange, powerful magic. And bring him back safely.
Simple enough. Except he's being hunted by ruthless assassins. And they have magic like mine. I might finally get the answers I've wanted my whole life. But what-or who-am I willing to sacrifice for it?
