Wizardry Park - The Island

Thirty witches, the last of the wizarding kind, are marooned on a tropical island with a one year window of opportunity to regain their freedom. Granted, freedom is the least of their worries, as it is up to them to repopulate their race. Minerva McGonagall, of course, has an idea, though she didn't count on Hermione Granger thinking so highly of it.
