It's the near future. Computers are faster, cars run on fuel cells, and there's not much to do in the small town of Easter River if you're thirteen and not into team sports. Helen Chan-Fisher is happy enough trying singlehandedly to save the world's remaining amphibians from chytridiomycosis, but her friend Jordan O'Blenis is at a loose end. He may be a genius, but it seems like no matter what he tries to do, his robot-building older sister Cassie did it first. Then he has his great idea, an idea so great even Cassie hasn't done it. He'll write a programme for a virtual supercomputer, one that can live on the Web, and grow and spread and learn .... Jordan calls it Cassandra. Helen calls it a virus. Cassandra calls home...and when agents of the government security agency Bureau 6 try to seize her for their own purposes, it's up to Jordan and Helen to keep Cassandra from falling into the wrong hands.
K.V. Johansen was born in Kingston, Ontario, and is the author of numerous works for children, teens, and adults. She predominantly writes secondary-world fantasy, but is also the author of some science fiction and literary criticism, and of a collection retelling medieval Danish ballads. With an artist friend, she is also working on a manga-style adaptation of a short story set in the Blackdog world. Johansen has an M.A. from the Centre for Medieval Studies at the University of Toronto. Her lifelong interest in ancient and medieval history and the history of languages has had a great influence on her writing and world-building. Johansen was the editor of Stalin Versus Me, the final, posthumously-published volume of Donald Jack's "Bandy Papers" series. She is hard at work on more Torrie books and on further works set in the world of Blackdog, a secondary world fantasy for adults coming out in September 2011.
She has a house full of exotic trees, most of which have gotten too big to pretend to be bonsai any more. Her websites can be found at www.pippin.ca & www.kvj.ca .
