Former Naval Special Warfare Development Group orthopedic trauma surgeon Mark Thurman and preeminent scientist Claire Hodgson have discovered how to create human bones and heal fractures in days. They test their revolutionary methods on Mark's ex-SEAL Team colleague, John Bristow, who was shot and left for dead after an altercation at his farm. The search for suspects and a motive turns up hydrofracking extortionists,ex-military Special Forces, and agents of foreign governments. When things begin to go sideways it becomes apparent Bristow isn't the person he appears to be. However, Thurman owes him a debt--and he'll risk all to pay it.
