Covenant

The Hematoi descend from the unions of gods and mortals, and the children of two Hematoi pure bloods have godlike powers. Children of Hematoi and mortals--well, not so much. Half-bloods only have two options: become trained Sentinels who hunt and kill daimons or become servants in the homes of the pures. Seventeen-year-old Alexandria would rather risk her life fighting than waste it scrubbing toilets, but she may end up slumming it anyway. There are several rules that students at the Covenant must follow. Alex has problems with them all, but especially rule #1:Relationships between pures and halfs are forbidden. Unfortunately, she's crushing hard on the totally hot pure-blood Aiden. But falling for Aiden isn't her biggest problem--staying alive long enough to graduate the Covenant and become a Sentinel is. If she fails in her duty, she faces a future worse than death or slavery: being turned into a daimon, and being hunted by Aiden. And that would kind of suck.

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 gods—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. Finding their way past the barriers that guard the Underworld, searching for one soul among countless millions, and then somehow returning will be hard enough. Alex might be able to keep Seth from becoming the God Killer… or she might become the God Killer herself.

In order to save Alex, Aiden St. Delphi will do anything, including making war against the gods.

Being destined to become some kind of supernatural electrical outlet isn't exactly awesome - especially when Alexandria's "Other Half" is everywhere she goes.

"It's a beautiful day for a war. As the mortal world slowly slips into chaos of the godly kind, Alexandria Andros must overcome a stunning defeat that has left her shaken and in doubt of their ability to end this war once and for all. And with all the obstacles between Alex and her happily-ever-after with the swoonworthy Aiden St. Delphi, they must now trust a deadly foe as they travel deep into the Underworld to release one of the most dangerous gods of all time. In the stunning, action-packed climax to the bestselling Covenant Series, Alex must face a terrible choice: the destruction of everything and everyone she holds dear... or the end of herself."-- Page of cover.

As Alexandria approaches her 18th birthday, she finds that a fanatical order is out to kill her. Time spent with Seth leads to another mark of the Apollyon, signifying the approach of her awakening. As her birthday draws near, she must choose between love and fate as the gods prepare to reveal themselves.
