This story is a sequel to The chef's student
After Trixie undoing Luna's banishment with the elements of harmony. Twilight's life focused more on finding a cure that could separate Luna and Moon Nightmare from each other.
However before she could do anything, she first graduated school and gained an healthy dose of work experience in many different settings.
From the friendly neighborhood to the shady inner workings of the black market. Twilight's life as chef was about to start for real!
I recommend reading The Chef's apprentice and The Chef's student before reading this one.
