Asprin + Carroll + Rowling + never-too-old story of an introvert falling in real love with an introversive second half. The story is not exactly up to the task on any front. It's not funny enough, not outlandish enough, not teenage-accessible enough and definitely not tear-jerking enough.The only good thing the center of magical gravity is a door, not a carpet or a broom.It would had been even heavier crossbreeding of others' ideas.
