But as soon as the pair settles in Paris, an old friend arrives with news about a demon-worshipping cult called the Crimson Hand that is bent on causing chaos around the world.

Demons are now dogging their every step, and it is becoming harder to tell friend from foe. As their quest for answers becomes increasingly dire, Magnus and Alec will have to trust each other more than ever- even if it means revealing the secrets they've both been keeping.
