What Good Can Come From Blood Magic?

Lucky Hawke sold his soul to save his sister's life, but the witch, Flemeth, did not say how she would save her. Bethany, now in a cursed half-life, must either come to peace with her existence or let her brother explore darker paths in an attempt to rescue her from her fate. But nothing can rescue him from his. Featuring a nonbinary poly elf-blooded Hawke.
