Blue Vengeance [EPUB ebook] 

In the spring of 1964, troubled teenager Cookie Blue is found dead in the Red River. Blue Vengeance follows her younger brother Danny and Cookie’s friend Janine through a lazy Winnipeg summer, as they plot to kill the despised teacher they blame for Cookie’s death. Danny’s father is long gone, and his mother suffers from a debilitating medical condition. Her illness and self-medicated state free Danny from certain constraints traditionally put upon a young teenager by a parent…like committing murder.
