Séverin and his team members might have successfully thwarted the Fallen House, but victory came at a terrible cost - one that still haunts all of them. Desperate to make amends, Séverin pursues a dangerous lead to find a long lost artifact rumored to grant its possessor the power of God. Their hunt lures them far from Paris, and into the icy heart of Russia where crystalline ice animals stalk forgotten mansions, broken goddesses carry deadly secrets, and a string of unsolved murders makes the crew question whether an ancient myth is a myth after all.
