Everything about this feels far too glib. We have a schoolgirl who might as well be Buffy mark II, struggling at school, traumatised by her mother having recently died. She has strange dreams, and when attacked by some bullies at school, demonstrates superpowers then finds herself time-travelling to some pirate ship, under attack by some superpowered evil pirates.
The Unwritten is a Vertigo title that looks at how the world of fiction interacts with the real world. As the narrative unfolds, we are presented with the possibility that characters from stories can become real and manifest in the physical world, though of course that physical world is itself only a comic strip representation.
