I am writing a story about a girl who goes to assassin school.what would be a good title for it?

This story has a lot going on.Mostly full of her making friends,helping out those who have a hard time coping with what they're doing in some way (for example,one boy is being forced into being an assassin and he is training to be an assassin but he's a hemophobe) and at some points in the story she is falling in love.I'm trying to think up of a good story title and I've tried for a while but I cant think of one that I'm satisfied with!!Can someone help me by giving me a good story title for this??

Assassonette?
Assassin's seed?
The silent apprentice?

Just throwing in a few ideas there
