This series gets increasingly juicy. I love the bits of mysticism along with the solid plotting and wonderful characters.
Lassair, the main character, is developing her healing skills, and in this adventure, is sent to Spain to her mentor Gurdyman's home town.
The world of Muslim/Christian Spain in the beginning of the Second Millenium, Common Era, is lovingly detailed, and the characters come very nicely to life. ( )

Medieval realism knocks on the door of medieval mysticism

A presence fills the alleys near Gurdyman's house. A vagrant is found dead with a lustrous pearl in his hand propped up against the wall outside Grurdyman's house. Gurdyman is panicked. He knows he's being called back by his past to the places of his childhood and his growth in magico-mystical knowledge.
Lassair is feeling isolated. Jack Chevestrier has sent her away and she finds no place but Gurdyman's. When Gurdyman asks her to accompany him to Spain, despite it being near to winter, she agrees. After all healer Lassair is Gurdyman's pupil and as is pointed out, 'it is a part of his duty to ensure that [she] encounter others who are so much further advanced in the arts.’ These words are those of Lassair's aunt, healer Edild. Edild is now married to Hrype, who first introduced Lassair to Gurdyman. Hrype knows what Gurdyman is and what Lassair could be. He also feels that Gurdyman is exposing Lassair to danger.
Along the road to Santiago Lassair and Gurdyman turn off. New fears and experiences become joined. Lassair has become part of what Gurdyman must do. An atonement? Lassair's journey becomes more complex. Lassair and Gurdyman have been pulled into a hidden mystic community and Lassair is being tested.
Meanwhile Jack and Hrype both meet after sensing a malicious presence in Gurdyman's vacant home. They feel the need to follow that presence towards Lassair. Their journey that will involve Lassair's grandfather Thorfinn, an "Icelander whose nickname was the Silver Dragon" who'd given Lassair "a powerful heirloom known as the shining stone."
This is a novel full of unexpected twists and turns. I must admit I'm a tad conflicted. Reading this I felt like I'd wandered into a lookalike set of Shrangrila, although located in medieval times in the Pyrenees, where esotericism is practiced in a secret valley hidden beneath and beyond the mountains.
I am also unsure of how I feel about the ending?... Lassair obviously must follow her path, even if (as I think), Gurdyman has been somewhat duplicitous in everything. Is Lassair cautious enough? She hasn't been that before. And what of Jack? How will things eventually resolve? We are left with the thought that Jack might be more than he appears. That his solidness is meaningful in some way. For a brief moment there seems to be some sort of positive, even hopeful tension between him and Lassair.
Some of the community Lassair encounters seem to think that some deaths are expendable in the big picture. I do wonder if the healer in Lassair will come into conflict with this viewpoint.
Change and growth are a pivotal point for Lassair. How she gets there is dangerous and challenging.
I must say I'm glad I read the previous novel in the series as there might've been gaps that would've annoyed me otherwise. I am also anxious to see where Clare is leading us.
