Monster at the Library Gates

As Minerva McGonagall struggles once again to not hex the insufferable Gilderoy Lockhart, one Hermione Granger makes a crucial discovery. What she doesn't realise is that a monster is in wait outside the Library, and only the intervention of Penelope and her own brainpower will keep her alive. With cameos from Lockhart, Madam Pince, Ginny, and a certain diary. Canon compliant.
