This has to stand for all 5 'Merlin' books. The first two I have read long ago and several times and only just discovered there were three more. I really enjoyed two of the three but the last one was lacking in plot so a bit disappointing. It's a seductive world and attractive characters. The best part (as with the 5 Amber books) shows the protagonist exploring and learning how to operate. Perhaps too effectively because with both sets, by the end, they are a bit too powerful and the empathy (mine at least) is a bit lost.
