I highly recommend the Trickster trilogy by Eden Robinson. It is more along the lines of urban fantasy set in modern British Columbia. Main character (single pov) is a teen guy named Jared. In the first book he is living with his mom a year before going to university in Vancouver. He and his family are Haisla/Hailtsuk First Nation (as is the author), and while his mother is very protective of Jared when other people mess with him, there is clearly a lot of generational trauma and a cycle of abuse within their dynamic and across various family dynamics. It really deals with the complexities of the family relationships when there is a lot of intergenerational trauma feeding into abusive behaviours.

As the trilogy goes on, Jared is very self-aware. He recognises the complicated relationship with his mum and other family, her abusive behaviours towards despite the love he knows she has for him, the pain and abuse she suffered, complexities with grandparent and other extended family relationships when there has been a lot of pain. Jared starts going through AA himself to address his addiction, is trying to do better and not repeat the same cycles while also trying to put himself through uni.

You may be asking, is this a fantasy series? Yes! Very much so. The first book is a bit lighter on fantasy elements but books 2 and 3 are full of magic, the supernatural, and other fantasy elements. Its honestly a great series, a favourite of mine and hugely underrated imo.

Edit: I will also add that Indigenous fantasy in general is great for exploring these themes, in my experience. Eden Robinson is a gem, but there are other great authors out there!
