Thank you all for your comments. There were so many wonderful ideas, and I wish I could have written them all. The short story I wrote is called "Wicked Witchcraft", and it features Bella and Harker.
Dark magic is brewing at the New York University of Witchcraft. Witch-in-training Bella teams up with angel Harker Sunstorm to get to the bottom of it. Wicked Witchcraft is a new short story set in the Legion of Angels world.
I hope to add more LoA world stories for my fans in the future.

Last year, I wrote a short story featuring Nyx, the First Angel.
Soon I'll be writing another short story set in the Legion of Angels world. Please comment here to let me know which character you'd like to see star in this story.
