Weird Story Idea

So …

There are some kids who go to magic school in an alternate dimension – think Whitehall rather than Hogwarts.  Something goes spectacularly wrong and they find themselves dumped on Earth instead.  The good news is that they have magic still; the bad news is that they don’t have enough to reopen the portal and get back home.  They get very lost until they discover, through one of their friends, that they can tap the electric power grid to power their spells and reopen the portal. 

(I have the vague idea that the school’s alpha-bitch will be knocked down a peg or two because her magic is greatly reduced in our world, leaving the harder-working students with an edge.)

The discovery brings forth a new threat – a gang of rogue wizards on Earth, who have been secretly preparing an invasion of the magic world (they’re responsible for the portal accident, indirectly), and they try to stop the kids.

How does that sound?
