Veronica is trapped in a web of betrayal, fear, and darkness. That's expected when you are the most wanted villain in the world, called Equinox. She is a paradox of darkness and light.
Finn is hope. His life is one of a savior, a hero. His mission is to save others from Equinox, and to prevent her from torturing and killing innocent people. Nobody knows his secret, not even those closest to him, and especially not those he loves more than anything.
Oh, and did I mention, they're married. And they are blissfully unaware of the identity of the other.
