Prologue

The veil between the human and spirit worlds is thinner than you think. When the Guardian, who's job is to make sure both worlds remains separate, accidentally lets a human child slip through, he rushes to get things back to normal, but it's too late. The damage has been done. As the child grows, she begins to develop spiritual abilities, and one All Hallow's Eve, she slips back through the veil. But this time, it isn't the Guardian who catches her, it's an ill-tempered wolf spirit desperate to get the Guardian's Apprentice, a timid spirit boy, removed from that office.
