HI TO WHO EVER YOU ARE

Diana Bloodrose seems innocent enough, but thats because no one knew her dark past. The people she lost. However even she didn't know how powerful she is. She ran to Maryse lightwood and through her she became Isabelles parabati, she was meant to meet the other two lightwoods when she turns 18. But when your also friends with Clary and Simon things take a different turn.

(Btw she lives with Magnus)
