So this is a very brief summary of what happened between chapters 22 and 23 for those of you who actually care.
After rescuing Alec from the old house/cabin thingy, Clary used her awesome doctor skills to heal Alec. He was still weak though and was taken back to the mansion to rest by Magnus. Jace and Isabelle told Maryse about what had happened and she made a case for court in her sons defence. In the court she accused Hodge of what he had done. She won and Hodge was sentenced to jail for life. Maryse also got Isabelle, Jace and Clary cleared for having shot Alec kidnappers in the cabin. Alec was still wanted for killing people (refer to around chapter 1) but nobody knew what he looked like, so he was basically free.
Tell me if I'm missing anything!
And I have added a poll to my profile page that is wither you want a sequel or not. :3
