A Blackbird in Twilight — Freda Warrington

The Serpent M'gulfn is dead, yet the Earth of Three Planes faces new dangers. Melkavesh, powerful sorceress and daughter of Ashurek, has come to claim her birthright―but she bargains without Xaedrek, the seductive, charming, and ruthless Emperor of Gorethria. The clash between them will bring other lands to ruin, claim innocent victims, and even cause the moons to fall.

The fourth volume of Freda's first fantasy series creates an eerily atmospheric world.
