Astrid Magnussen, the teenage narrator of Janet Fitch`s engrossing first novel, White Oleander, has a mother who is as sharp as a new knife. An uncompromising poet, Ingrid despises weakness and self-pity, telling her daughter that they are descendants of Vikings, savages who fought fiercely to survive. And when one of Ingrid`s boyfriends abandons her, she illustrates her point, killing the man with the poison of oleander flowers. This leads to a life sentence in prison, leaving Astrid to teach herself the art of survival in a string of Los Angeles foster homes.
