Darkness Falls

Three months have passed since the disappearance of Dark Horse's enigmatic team leader Erik Larson.  Brock Cahill, the team's youngest member, is summoned in the middle of the night by a cryptic text to Baltimore harbor where he discovers the unthinkable.   Larson is holding a woman hostage, demanding that Brock take him out to end the standoff.  

Meanwhile, Brock's father, retired Marine special forces operator Tom Cahill, finds himself caught up in an international incident while on a mission's trip half a world away in Africa.  A split-second decision drags Tom back into his former life and sets him on a path back to the United States where he must find Brock. 

If he can find his son, Tom will need Brock to provide answers as to why he and his team breached a highly classified server repository at Langley, before a shadow faction in the CIA hunts the team down and renditions them for their crimes.
