This question is related to City of Bones, a book written by Cassandra Clare as part of her Mortal Instruments series. I read these books a long time ago, but I believe Jocelyn decided that the three of them (Clary, Luke, and herself) are going to the farmhouse for the rest of the summer. That obviously never happened because Jocelyn was attacked by a demon and then Clary become a Shadowhunter.
