On the Attack
Ryan Kaine is on the attack…
Hunted by the law and driven by guilt, Ryan Kaine’s mission is to protect the innocent, whatever the cost.
When Angela Shafer’s stalker threatens to kill her, she turns to The 83 Trust for help.
Kaine vows to deliver justice, but when he reaches Angela’s home too late to prevent a terrible atrocity, the mission becomes deeply personal. Calling in his most trusted men, Danny Pinkerton and William Rollason, Kaine learns that, to keep Angela and her daughter safe, he must take down an entire criminal organisation.
As an underworld kingpin and his brutal thugs close in, Kaine will need every ounce of skill, courage, and resolve to survive.
Will Kaine justify calling in more favours from former military contacts and reluctantly bringing Lara on a live operation, and still keep everyone safe?
