Edge of Forever (On the Edge Duet #2)
Jacob Chance

Now, forced to live without the person I've come to love the most, I feel more alone than ever.
And if missing Belfast and trying to navigate my life without him isn't difficult enough, every direction I turn danger lurks--waiting for me.
No longer able to tell friend from foe, everyone is a suspect.
But I won't stop until the person responsible pays.
