Deep State (The Acer Sansom Novels Book 4)
Acer Sansom has discovered that the daughter he thought was dead is alive and well. He knows where she is, and he wants her back. But the Turkish organised-crime boss under whose protection she is living requires Acer to do a job for him first - to settle a debt.
With limited options - each of them endangering his life - and a ticking clock, Acer is destined to find out how far he will go to get his child back and that luck has its limits.
