Ian Irvine's The Way Between the Worlds, View from the Mirror volume 4, the last in the series. I waited awhile to read this last book, having finished the other three over a year ago. It was so worth waiting for. A great ending to the series. If you're looking for a fantasy series that's a little different, I'd recommend these books.
And now I'm watching 13 Going on 30. oh so dumb, but funny anyways.
