Bound To You

Elizabeth Fairchild and Amelia Carstairs, have lived the lives of normal Shadowhunters, if you can count that life as normal. Both being bound to each other with their lives, baring the parabatai rune, they live a somewhat simple life. They've left the London institute as young little ladies, Elizabeth leaving her sister and Amelia leaving her own brother, to become great Shadowhunters and be trained by Nephilim's best in idris. The day they come back to the London institute, they encounter things they have never had heard of before. A shapeshifter had moved into the institute, she speaks of a man named the magister, and clockwork creatures that seemed like unbreakable toys in the Magister's hands. What will they do? Were they trained good enough? Can they live to everyone's expectations? Or will they flee back to idris, abandoning everything and everyone once again.
