It’s against the rules for a Guardian to fall in love with their mortal charge, but it’s too late for Seth, the supernatural playboy assigned to look after Genesis Green.

Because the night Genesis crawls from the wreckage of her boyfriend’s totaled SUV, just before she slips into the darkness, Seth calls out to her, promising everything will be okay. It’s this mysterious voice that pulls Genesis back from the brink, and when Seth finally steps into her world, Genesis is just as drawn to him as he is to her.

When she begins having strange visions—something she attributes to the head trauma she suffered from the accident—the Guardian Council, an otherworldly force of good, reaches out, asking for her help.

If Genesis agrees, she will engage a line of enemies stronger than any mortal has ever known, and if they learn she is helping to minimize or undo their damage, she will become their main target. Even with supernatural protection, there’s no guarantee Seth can keep Genesis safe. All he can see is everything that might go wrong should she agree to help them, and losing her would be the end of him.

Faced with an ultimatum, Genesis must choose between the Guardian she might be falling in love with and a mission that could bring her life the meaning she’s so desperate to find.

But what happens when the line between reality and the celestial becomes so blurred it’s impossible to determine who’s real and who’s otherworldly, and worse: who's good and who's evil?

Fans of the Twilight and Hush, Hush sagas will revel in this epic urban fantasy trilogy detailing a battle that has raged for millennia.
