Elwynn shows up on Mark’s door after being absent for a while, frantic. She reveals to him that he needs to marry her, or else a minor Sidhe of the Winter Court will force her to marry him, which will result in their deaths. Mark refuses to do so, believing there is another way, and heads to New Haven to collaborate with Charlie to find it.

Along the coast of Connecticut a strange storm has blown in, and what appears to be snow falls from it. When this snow touches the bare skin of a person, that person loses control of themselves, acting out violently. From Bridgeport up through Branford cities and emergency personell have their hands full dealing with this.

At The Magic of Books, Mark and Elwynn meet with Charlie to discuss his problem. William was there to discuss an investigation he was on. Kris comes by because something about this storm is familiar to him. While in the bookstore, the paramedic Calliope takes refuge after her partner starts acting out. The storm gets worse.

Elwynn explains that when her and the “Baron” Oledrin were both Wyldfae, they were to be married. Once she was raised to the Sidhe of the Summer Fae, her court protected her from having to follow through with the marriage. After some time, Oledrin was raised into the Sidhe of the Winter Court, and their engagement was forced by the courts to move forward. Once the marriage happened, both her and Oledrin would die now that one was aligned with Summer, and the other was aligned with Winter. However, this would be a victory for the Winter court, since Elwynn was much more influential in the Summer court than Oledrin was in the Winter court. In fact, Oledrin was only raised to the Winter Sidhe because of this obligation that Winter could exploit.

Elwynn continues to explain that Mark’s mentor had married her, stalling the marriage between her and Oledrin. This kept Oledrin at bay while Mark’s master was alive. But now the Baron Oledrin discovered Elwynn’s husband was dead, and he’s pulling out all the stops this time in order to make her his wife – even though it means his death and hers. But if Mark were to marry her, this would once again keep her safe.

The group does some reasearch and hashes out various ideas to see what can be done about this. The Baron is not a reasonable man, and in fact is responsible for this storm. This is the same storm he summoned decades ago when he came after Elwynn previously – this is what Kris remembered. They cannot hide behind Charlie’s wards forever though; the madness outside continues to grow and as night falls the group is witness to Black Court vampires roaming openly through the storm, taking advantage of the chaos to have their own fun.

It is decided that Elwynn will have to die. Her death will free her from her promise of marriage to the Baron Oledrin. Charlie and Calliope work together to create a potion which will “kill” her, but also allow them to bring her “back to life” once the Baron has seen her dead for himself. The plan works, and the Baron retreats with his storm. Calliope and Charlie succeed in removing the poison from Elwynn’s body and bringing her back to life. Everyone goes their separate ways again, blissfully unaware of the consequences which their actions have wrought.
