Invisibilitatem Potionem

Harry Potter and Draco Malfoy have been married for two years now. Since then, they've both been back at one of the least unlikely places along with Harry's best friends Ron Weasley and Hermione Granger, teaching at Hogwarts School of Witchcraft and Wizardry.
Draco is a potions master, Harry is following in McGonagall's footsteps and teaching Transfiguration, Hermione's Magical History and Ron is heading up the sporting department at the school.
But, when Draco realizes that teaching isn't always simple or easy as it's cracked up to be, Harry and his friends must help him so that he can get his students to pass their end of year exams.
Also, there's the matter of Pansy Parkinson also teaching at Hogwarts as well and Harry having some issues with one particular student.
Really, there's quite the happenings going on at Britain's best magic school and it's going to lead to some eventful times.
Let's just hope that it doesn't all blow up in Draco's face...
