Return of the Trickster - Eden Robinson

All Jared Martin had ever wanted was to be normal, which was already hard enough when he had to cope with Maggie, his hard-partying, gun-toting, literal witch of a mother, Indigenous teen life and his own addictions. When he wakes up naked, dangerously dehydrated and confused in the basement of his mom's old house in Kitimat, some of the people he loves just think he fell off the wagon after a tough year of sobriety. The truth for Jared is so much worse.
     He finally knows for sure that he is the only one of his bio dad Wee'git's 535 children who is a Trickster too, a shapeshifter with a free pass to other dimensions. While his ex is happy he's a magical being, everyone else is upset or in mortal danger because he has accidentally unleashed dark forces—the scariest of which is his Aunt Georgina, a maniacal ogress hungry for his power, who has sent her posse of flesh-eating coy-wolves to track him down.
     Soon Jared is at the centre of an all-out war—a horrifying place to be for the universe's sweetest Trickster, whose first instinct is not mischief and mind games but to make the world a kinder, safer, place.
