Free Fall
Frank Ranger has a score to settle. And he always pays his debts.
Former Marine Frank Ranger has spent years hunting the man who killed his wife.
Now he comes face to face with his mortal enemy in Hells Canyon—America's deepest gorge, a brutal wilderness where survival is always in doubt.
Ranger isn’t worried about the danger, he’s focused on just one thing—living long enough to take revenge on the man who destroyed his family.
But that’s not going to be easy.
Trapped between a merciless river, sniper fire from the ridges, and a killer for hire whose loyalties shift with the wind, Ranger is outnumbered and outgunned.
With elite mercenaries closing in from every side, he is determined to fight to the bitter end—because some debts can only be paid in blood.
Free Fall – book 4 in the brilliant action thriller series featuring Frank Ranger. Perfect for fans of Lee Child, Jason Kasper and David Archer.
