Blood Fae by Meg Xuemei X.

I’d dance on a razor’s edge for my mates, but the Fae kings are no longer mine.
They belong to the usurper queen, bound by her black magic. Rydstrom and Baron have forgotten what I once meant to them. The Winter King, however, remembers me, but he’s embraced the dark side.
The world isn’t big enough for all of us—it’s either me or the kings.
So, I’ll lure them to Hell’s inferno to finish what they started in the Wild Hunt—to hunt down their mate to the bitter end.
