Query: The best book Penman has written - Unforgetable

This book far outshines her other books (which are great) and shall forever live in my memory as my favorite of her books. The story of Llewelyn Fwar & Joanna is so magnetic. The book draws you into Wales, it gives you views of King John and so many others that were before pictures in a history book, that now are alive and living. People you will never forget. When I go to England it will be more than a trip for me, it will be a meeting of old friends. A chance to walk the streets these people once walked. To that I say - Thanks Ms. Penman for taking me for a visit - how much I enjoyed it! She is a marvelous writer!!! Please read this book!
