Power is up for grabs as the Harrigans and Stevensons, two warring London crime families, clash in ahug-or-be-killed battle that threatens to topple empires and ruin lives. Caught in the crossfire is Harry Da Souza, the street-smart 'fixer' as dangerous as he is handsome, who knows too well where loyalties lie when opposing forces collide. As kingdom goes up against kingdom, lines will be crossed - and the only saving grace is a bet-your-life guarantee: family above everything.
