This book explores a part of history that very little people know about. It is interesting how Penman handles the romances between Joanna and Llewellyn and John and Isabelle, given the age differences between them. But even as teenagers the central characters speak as adults. The romance between John and Isabelle is slightly hard to comprehend as today it would certainly be called paedophilia. What could a 12 year old possibly have that a 32 year old man could be interested in? But in the 12th century such marriages were common and we cannot judge them by todays standards.
