Enjoyed “The Winter King”.Disillusioned by”Enemy Of God”. Always understood that Tristan was the son of the King of Loonois and that his mother was Blanchefleur , sister to King Mark of Cornwall – which makes King Mark his uncle and not his father . Tristan was offered the hand of the Princess Iseult for slaying a fierce dragon that had been ravaging Ireland but chose to take her back to Cornwall to be the bride of his uncle , whose champion he later became . Unfortunately , he fell in love with Iseult . No doubt you are familiar with the legend , so why have you chosen to ignore it or are you using artist’s licence as it were ? I do enjoy your books generally however. Do keep writing as the spirit moves ! All best wishes . Robert .
