That Devil Ambition

There is only one school worth graduating from, and it creates as many magicians as it does graves…
First in his class and last in his noble line, Fabian Galloway’s only hope of a good future is passing his elite school's honors class. It’s only offered to the best thirteen students, and those students have a single assignment: kill their professor.
If they succeed, their student debt is forgiven.
However, if an assassination attempt fails or the professor is alive at the end of the year, the students’ lives are forfeit.
And dealing with the professor, a devil summoned solely to kill or be killed, is no easy task.
Fabian isn't worried, though. He trusts his best friends—soft-hearted math genius Credence and absentminded but insightful Euphemia—to help. After all, that’s why he befriended them.
As the months pass and their professor remains impossibly alive, the trio must use every asset they have to survive. Or else failure will be on their academic records—and their tombstones—forever.
