 This prequel short story gives further insight into the surviving free Winterians, as they search for the magical conduit that will restore their kingdom to their people and free the Spring kingdom's enslaved people. This story takes place directly before the events that the first novel of the central trilogy, Snow Like Ashes, begins with. 
 As I have already read two books from the series no new information was presented to me here and it didn't really provide me with any emotions, either negative or positive, because of that. If you are considering delving into the Snow Like Ashes world, then this would be a great place to start but if you are already familiar with it then this is a bit of a pointless addition.
