For Lillian, being the last Lightwood alive didn't mean much. The path ahead of her was the same as all Hunter soldiers: kill as many Vampires as you can before they kill you. She is simply a future casualty in this never-ending war with this heinous species-- that is until she catches wind from a mysterious blue eyed Vampire that the Hunters had signed a ceasefire; meaning this unkillable creature was now her ally.

Alexander never thought he would find himself trapped in an alliance with the Hunters. He also hadn't been foolish enough to believe he would receive everything he could ever desire from the treaty - the ultimate weapon- his little monster.

As Lillian continues her quest to full fill her legacy, mysteries from the past continue to unravel until only one thing is for certain: nothing is as it seems, and death is around every corner.
