VOICES ON THE BRINK Tom Marshall Toronto, Macmillan, 1989. 224pp, paper, $14.95 ISBN 0-7715-9913-7. CIP Adult Reviewed by Ted Monkhouse. Volume 17 Number 4 1989 July Tom Marshall, born in Niagara Falls, Ontario, is a professor of English at Queen's University. This, his third novel, follows Rosemary Goal (Oberon, 1978) and Adele at the End of the Day. One suspects that this novel is somewhat autobiographical, since the detail, locale, era and circumstances seem 100 accurate for the regular observer-writer. Four young friends people this novel set in the 1950s in the still seedy, touristy Niagara Falls of Ontario and New York. Bars, sex, girls and drugs against a staid upbringing occupy the minds and recreation of these teenagers. Each drifts toward the brink (as in the title) of disaster and succumbs. Accurate, coarse language and vivid sexual imagery and description make this a novel primarily for an adult audience. Some will find it offensive but realistic with no holds barred. This novel measures up. Highly recommended but not for general tastes. Ted Monkhouse, Wellington County Board of Education, Guelph, Ont.
