In reply to purple sue:
Sand Point Middle Hope West Buttress area is good for loads of short pitches in the D - HS range. The climbing is short lived (8 - 10m) but decent, good for easy communication if your novice is of a nervous disposition. It is tidal though so you need to time your visit right to make the most of it (no abseil required). It is fairly recently developed, you'll find topos amongst the photos on the UKC crag page.
If you're confident in your novice's ability to handle exposure then as others have suggested some of the long routes at Wintour's Leap would be a memorable introduction to Trad.
If you go to Sand Point and your novice is getting confident try my route
Sandweto (VS 4b) softish VS and good moves for all of its short length.
Hope you are keeping well, must catch up for a climb at some point this Summer (I've finished term now, so have some flexibility over the next few weeks).
