We Are Bound, You And I

The Between. The purgatory where the dead are divided by their cause of death, where they become a bit more than human and a bit less than dead.
Will Herondale, Naturi, died of old age, and now goes by the name of "Deimos". Cloaked in raven's feathers with wings as black as night, he hides his face behind a mask.
Jem Carstairs, Inferni, died in a final blaze of glory, saving the life of Tessa Gray. Caught between Shadowhunter boy and Chinese dragon, he fights as a deadly silver beast.
Parabatai in life. Enemies in death. Each has killed the other twice, without realizing who they are to each other. Now they face each other for the last time-but a single familiar face might just be enough to awaken them to their pasts again.
