Apollyon (Covenant Book 4)

Fate isn't something to mess with - and now, neither is Alex. Alex has always feared two things: losing herself in the Awakening and being placed on the Elixir. But love has always been stronger than Fate, and Aiden St. Delphi is willing to make war on the god - and Alex herself - to bring her back. The gods have killed thousands and could destroy entire cities in their quest to stop Seth from taking Alex's power and becoming the all-powerful God Killer. But breaking Alex's connection to Seth isn't the only problem. There are a few pesky little loopholes in the whole 'an Apollyon can't be killed' theory, and the only person who might know how to stop the destruction has been dead for centuries.
