Blindsided (The Guardians #2)
Hope Anika

The last person CIA Agent Rafferty Blackheart expects to find while retrieving the message left for him by his dead partner is the childhood friend he left behind two decades earlier. But the woman he discovers bears little resemblance to the girl he remembers, and even though the sight of her breathes life into everything he's spent years fleeing, walking away from her is an impossibility.
Because Rafe is on a mission, one he can't complete without Ruby. So no matter their dark history, their mutual distrust, or the intense, unwelcome pull between them, they must come together. To avenge the death of an innocent; to save a child. And to stop a mad man bent on reshaping the human race.
Before it's too late.
A dark, edgy, steamy thriller with characters you won't forget…contemporary romantic suspense at its best.
