I love the part where Gwenhwyvar sets of for the forbidden forest and meets Bedwyr who was secretly sent there by Gwalchavad to meet her and distract her from her quest, and then Gwenhwyvar remembers that she forgot to lock the front door to her cottage before she left so she has to go all the way back through the valley of the goat people.
OK, I confess I never read Lawhead's Pendragon Cycle.
