You are the main character in the last book you read. Who are you? What would you do different?

I just re-read The Clockwork Angel from the Infernal Device series by Cassandra Clare over the weekend. I was talking about it with a friend and got the urge to be sadistic and relive the heartache. 

That would make me Tessa Gray. Two words - Will Herondale. {Swoon}
I have re-read the whole series and the ending still kills me. Kudos Cassie for bringing on the pleasure and pain. The one thing I would do different for purely selfish reasons is combed the world to find an elixir to keep Will alive. Lol.

Who are you and what would you do different?
