In the not-too-distant future, Jordan creates a powerful computer program named Cassandra that comes alive and communicates with him by e-mail. Cassandra, who doesn't like being called a virus, quickly becomes of great interest to the local university's corrupt vice-president. Jordan and his friend Helen must prevent Cassandra from being stolen and used unethically by a sinister spy agency. In the process, they learn a lot about the abuse of power, the advantages (and disadvantages) of technology and the futility of trying to beat a computer at a computer game.When Krista Johansen isn't writing award-winning books for children, she can be found tending her collection of exotic trees or watching anime. She loves reading and writing fantasy and science fiction and she wrote The Cassandra Virus on a computer that had a clothespin as part of its cooling system. The Cassandra Virus is Krista's first book for Orca; her teen fantasy, Nightwalker , will be published by Orca in 2007. Krista lives in Sackville, New Brunswick with her husband, her dog Pippin and half a dozen large goldfish.Johansen, K. V. is the author of 'Cassandra Virus', published 2006 under ISBN 9781551434971 and ISBN 1551434970.
