Jasper Andrews is in over her head. God and the Devil have disappeared from Earth, leaving humanity without hope. Il Separatio, the Entity of Neutrality, tries to restore peace through the intervention of its children, the Order of Vespers. They are tasked with maintaining the balance between light and dark, ensuring that no faction becomes too powerful. They think Jasper is the key to harnessing the power of Il Separatio, protecting the Vespers and maintaining the balance. —— Eighteen-year-old Jasper Andrews finds herself drawn into this superhuman world when a freak explosion exposes her to groups interested in secret abilities. When her family is killed under unbelievable circumstances, Jasper is the only suspect. She flees police custody and heads to New York City to lose herself in the crowds. Jasper wants revenge, but being chased by the police and superhuman bad guys, slows her down. While she’s in hiding Jasper becomes more volatile; she begins manifesting traces of her siblings’ abilities and begins to lose control. The Order of Vespers has decided she’s too dangerous and too important to leave unguarded and capture her. Before she can escape, the killers strike again, this time taking children directly connected to the Order. Jasper is forced to choose between her vendetta and the lives of the Vespers and humanity.

The Order of Vespers is in turmoil. Their most powerful supernatural members have been kidnapped by a cult hell-bent on destroying the cosmic balance. Its members are revolting and their leadership, The Circle, is hanging on by a thread. The one person who can save them, Jasper Andrews, has been missing for over a year. Jordan McAllister gets a lucky break when one raid turns up more than they could have hoped for: a way to bring back his dearest friend and partner-in-crime. While members of The Circle are against using magic to restore her, Jordan is convinced that Jasper has a larger role to play. He believes that she can stop the kidnappings, ferret out the traitors to the Order, and save the world. The Circle must decide whether to trust in dark magic and a friend that may no longer exist or to forget her and try to save the Order themselves.

Since Jasper Andrews took up her mantle as an assassin of the Order of Vespers, she’s seen just about everything. She came into supernatural abilities that belonged to her deceased siblings, chatted with deities, and trained with an immortal mentor. As if life wasn’t mind-boggling enough, she’s been put in charge of ending a cult hell-bent on unleashing chaos on humanity. Jasper finds herself relying on the one person who has the power to hurt her but can’t seem to fight the magnetic pull between them. Now, they must stage a rescue mission and defeat their greatest mortal enemy while avoiding heartbreak. No big deal, she’s saved the world before…sort of. This should be a piece of cake.
