Content note: death.
This story explored a darker side of magic and magic use, drawing analogies with drugs and drug use. Mali doesn’t approve of Nick’s getting mixed up with that sort of stuff — but when he turns up dead on her doorstep, she’s not going to let her friend’s death go unavenged. Of course, nothing is ever as easy as that, and the more Mali protests against the use of magic, the more inevitable her own use of it is. This was a pretty dark story, all in all.
