Clary Fray reluctantly leaves Simon Lewis to be guarded by Maia Roberts and Jordan Kyle for his safety.

Simon is kidnapped by Maureen Brown and her vampire aides to be her groom, but Raphael Santiago frees and helps him to come to Alicante.

At Alicante, Emma and Julian Blackthorn are interrogated using the Mortal Sword, Clary comforting the former when she breaks into tears.

Choosing to accept her Morgenstern heritage, Clary claims Heosphoros, the twin of Sebastian's Phaesphoros, as her sword.

The Seelie Queen, now allied with Sebastian, sends Meliorn to ask the Downworlder Representatives (Jocelyn Fray, Luke Garroway, Magnus Bane, and Raphael) to join them; when they refuse, he brings them to Edom, the realm of demons.

Confronting Sebastian, Clary pretends to agree to rule by his side but then stabs him with Heosphoros, reverting him back momentarily to the brother she could've had, Jonathan Morgenstern, who destroys the Infernal Cup before he dies, killing the Endarkened, including Luke's sister, Amatis.
