For most people, the story of their lives is just that: the accumulation of time, encounters, and actions into a cohesive whole. But for an unfortunate few, that day-to-day existence is affected - perhaps infected is a better word - by memetic incursion: where fairy tale narratives become reality, often with disastrous results.

The world of Faerie never disappeared: it merely went into hiding, continuing to exist parallel to our own. Secrecy is the key to Faerie’s survival—but no secret can be kept forever, and when the fae and mortal worlds collide, changelings are born. Half-human, half-fae, outsiders from birth, these second-class children of Faerie spend their lives fighting for the respect of their immortal relations.

Children have always disappeared under the right conditions - slipping through the shadows under a bed or at the back of a wardrobe, tumbling down rabbit holes and into old wells, and emerging somewhere...else. But magical lands have little need for used-up miracle children. Nancy tumbled once, but now she's back. The things she's experienced...they change a person. The children under Miss West's care understand all too well. And each of them is seeking a way back to their own fantasy world.

The Price family has spent generations studying the monsters of the world, working to protect them from humanity - and humanity from them. Enter Verity Price. Despite being trained from birth as a cryptozoologist, she'd rather dance a tango than tangle with a demon, and is spending a year in Manhattan while she pursues her career in professional ballroom dance. Sounds pretty simple, right?

Let's get one thing straight - Ivy Wilde is not a heroine. In fact she's probably the last witch in the world you'd call if you needed a magical helping hand, regardless of her actual abilities. If it were down to Ivy, she'd spend all day every day on her sofa, where she could watch TV, munch junk food, and talk to her feline familiar to her heart's content. However, when a bureaucratic disaster ends up with Ivy as the victim of a case of mistaken identity, she's yanked very unwillingly into Arcane Branch.
