Sage and Oren are sent to investigate rising tensions between witches and werewolves in the Jura Mountains. After dealing with murder, this case feels tame – punishment for their undeniable connection.

But neither expects to find evidence of worse: traces of old magic, tortured lost souls and a deadly fog that kills everything it touches. Cassandra Clare meets Rivers of London in this razor-sharp crime romantasy series. The perfect sequel to All the Hidden Monsters, set in both in Downside (the magical city existing beneath Manchester) and the French mountains.  Think addictive slow-burn romance, twisty crime and heart-warming friendships.
