I got the idea when reading TMI:COLS, when clary is going through Sebastian's things and notices a not that said 'my beautiful one' and she thought who would Sebastian ever be a 'beautifule one' to anyone. So this is my idea of when and how Sebastian found and lost love for the only time and how he found and lost his humanity... This is my first fan fic so I hope u like it

What if Clary knew Jace, her Jace, was gone forever, and all of the sudden, she realized that Sebastian was who she belonged to now? It starts right when Sebastian kisses Clary after he repairs Lilith's rune on Jace's chest. A different type of love? Can Sebastian really love? Rated M because it is super citric concentrated lemonade! No under age readers please!

Jonathan escapes from his father at the age of 12 and hides in a New York park, where he meets a sharp-tongued and clever girl with a very large scarf. Why can this mundane see him? Who could she be? oneshot.
