"Beginning Gliding" by Derek Piggot is a must. Get one from Santa and by the New Year your enthusiasm will be boiling over.
I spent many happy years standing around the launch point all day in cold freezing conditions to manage a 10 minute flight every weekend!! Eventually bought into a syndicate Pilatus B4 then spent 30 minutes at launch point for 5 hours flying per day!!.............a great way to get into flying and far better than worrying about an engine in the front....enjoy
