Stained Glass Angels: A Mortal Instruments Fanfiction

Miles from the nearest major city, live a different group of Shadowhunters. Their home is called the West Lake Institute where multiple Nephilim families police the rural communities of western Michigan.
15 year old Madlyn Carpenter and her father are assigned to aid the families of West Lake and expect ignorant and undertrained rednecks overrun with demons and other Downworlders. The father and daughter are surprised to find the Shadowhunters honest and kind, preferring friendships with Downworlders over strained alliances. Immediately the pair are accepted into the tight-knit families and join in their policing.
However, their arrival brings in new challenges unusual to the Shadowhunting community. For example: a young Mundane from a strong, fundamentalist Christian family begins the Ascension Training to become a Shadowhunters in order to wed his Nephilim fiancée. Next, a parabati Ceremony is put on hold when one of the teens involved finds a better partner in Madlyn. Then, upon hearing of the untraditional practicing of the Accords and Law, the Clave sends in the conventional and bigoted Finchly Redstone to supervise West Lake. All the while, different species are being created from Downworlders that never interbreed, including a child born of a sterile Warlock.
As dangerous problems arise both in the Institute, Mundane, and Downworld; loyalties will be questioned and facts long believed will become obsolete while fiction becomes reality.
