In this, the third of the Blackthorn and Grim novels, circumstances threaten to tear them apart. A young girl has been placed under Princess Flidais’ care, needing Blackthorn’s attention. At the same time, the girl’s father hires Grim to help rebuild a home, fallen into disrepair, on his property. It is some distance from his home with Blackthorn, but the money is too good to turn down. It doesn’t take long for Grim to realize that there is more to the job than meets the eye.
Meanwhile, Blackthorn is finally offered an opportunity to help bring the man who imprisoned her to justice. The problem is that in order to make it in time to testify against him, she will have to leave Grim behind. Torn between her desire for justice and her growing love for Grim, who is in danger, she is faced with an impossible decision.
Unlike most series, Marillier wraps up the loose ends with this book. Much as I loved Blackthorn and Grim, I would be content if this is the end of them.
