On the Rocks
Ryan Kaine is on the rocks…
One man’s quest for redemption becomes a desperate fight to save a boy’s life.
International fugitive, Ryan Kaine, still haunted by the deaths of eighty-three civilians on Flight BE1555, abandons his pursuit of exoneration to rescue a missing schoolboy.
Martin Princeton disappears on a Scottish mountainside, and Kaine is the boy’s only hope for survival.
Battling his own injuries and a bounty on his head, Kaine must convince a sceptical mountain rescue team to trust him while keeping his true identity hidden.
As he fights the clock and the brutal terrain, Kaine confronts his past mistakes and the possibility that this mission could be his last.
In a world where he’s public enemy number one, can Kaine use his special forces training and rapport with the locals to overcome his enemies and bring Martin home safely?
