Finding the Way Back to the Past

Will, Jem and Tessa find themselves up against weeping angels (unknown at the time to them what they are) and get sent into the future. Specifically the future where the Mortal Instruments takes place. [There is going to be another story called Finding the Way back to the Future that certain people from TMI will be sent to TID time]. There Will, Jem and Tessa meet the tenth Doctor.
