Isabella Amariah takes a little under a day to fly to Québec City from her teacher's home in Maine. She doesn't have to spend that long in transit, but the book she's fetching isn't urgent; as long as she's faster than international overland shipping it's worth sending her.
Witches are politely ignored by customs on undefended borders as long as no clans are giving either government particular trouble. As long as she's in the air, obviously a witch and not a human dressed up as one to play a stereotyped character on television, she doesn't even have to dip down and show her clan tattoo to prove that she's descended from those who give allegiance to the Olympic clan. (Clans still refer to themselves by geography, though her teacher is as Olympic as she and lives on the other side of the continent and cloud-pine hasn't gotten any faster recently.)
Isabella touches the symbol inside her left wrist: two concentric circles, two lines. It doesn't mean anything, it's just unique, simple, easy to draw on the floor in herbs or honey or lighter fluid for a spell that refers to the coven.
"If only you were a proper Harry Potter owl," Isabella tells Pathalan, "I could send you for the book, you'd be able to carry it all by yourself, and I could be working out the kinks in this latest impossible assignment."
"Perhaps you wish I were an albatross," says Pathalan dryly, coasting through the air in her wake. "To fetch and carry and be not a bit like you at all."
"No," laughs Isabella. "Owl's fine. Soft and see-in-the-dark."
"It's never dark," says Pathalan. "Never quite."
She approaches the city, and attracts attention; witches are known but hardly common. A teenager - not even old enough to look properly ageless and spectacular like Metis Imestha, her teacher, or even Ranata Ekamma, her mother - dressed in raggedy black silks that whip around her in the wind, soaring over the streets on cloud-pine, is more unusual still.
Isabella Amaraiah coasts to a stop outside the correct address - witches can benefit from Google Street View even when they do not use streets - and descends to ground level.
