The Indian and The Cowboy - The Indian and the Cowboy, #1

Myrya Blackstone, an orphaned aboriginal, is a brilliant mathematical student who arrives at a First Nations Reserve.  Beaten up and driven off the reserve, she is rescued by a young construction worker and reluctantly takes a cook's helper job at a nearby pipeline company, hiding her academic background. Myryra's work ethic transforms the construction workers' bigoted attitudes to 'Indians' and she gains support when young men from the reserve continue to attack her.
She exacts revenge on her attackers using wasps with comical results. After more attacks on her, she sneaks back to the reserve and uses an improvised explosive and white phosphorous to destroy a car with humourous results. Her revenge escalates to using eggs of Ascaris summ, a pig nematode, to attempt a serious infection of her antagonists. But her best conceived plans show the unpredictable effects of revenge.
