No rules. No choice. No turning back.

He played by the rules - until the only rule that mattered was survival.

Recovering from a gunshot wound that nearly cost him his life, DCI Tom Douglas isn't focused on himself - his concern is for his brother Jack, who seems to have vanished without a trace. Jack's past is as dangerous as it is complicated. Years ago, he faked his own death to escape an organised crime group, and ever since, he's been living in the shadows, always one step ahead of those who want to hunt him down.

Now, Tom's worst fears are coming true. Has Jack's past finally caught up with him? And what does that mean for his family? Tom has to find them, but the answers he seeks are hidden in a brutal underworld - one more threatening than anything Tom has faced before.

With time running out and his own life on the line, Tom must decide how far he's willing to go and how much he's prepared to sacrifice, knowing it will mean crossing a line he swore he never would.

But there is another player in this game - one who will stop at nothing to find the answers she seeks. And if Tom makes the wrong move, he, and everyone he loves, will lose.

He's spent his life chasing criminals. But to save his family, he might have to become one.
