This was an interesting set up novel. Nyx woke up in Tempe, Arizona, with no memories of the past, and a note that her apartment and tuition were paid for. She’s out of school now, and has found that no one can remember her, and she also can’t leave Tempe. Out of desperation, the next time she tries, she manages to slip out of regular Earth to a parallel Earth that serves as a gateway to the larger, magical universe. She’s been drafted as the Guardian to one of the gates that lets everyone travel between worlds.
This story is very much set up – learning a bit more about Nyx, how the gates work, and some of the workings of the other worlds. Nyx ends up helping to save some people, and making an interesting variety of friends – this definitely has potential, depending on where the author decides to take it next.
