“Two year's ago Sinclair's debut, Seventy Times Seven, was very well received, but this, his second, is even better. The language is fierce and unwavering, and the two protagonists, both strong women, are beautifully drawn...There is a touch of the John Grisham in the muscular energy that drives it, but Sinclair is a bleaker writer who never teeters into sentimentality. It is a hard, tough ride on the wild side that lingers in the mind.”
“'Fast-paced action, riveting characters and a plot driven by breathtaking violence, more twists and turns than Hampton Court maze and a spine-tingling sense of danger make Blood Whispers a leading contender for 2014's best thriller...Blood Whispers is Sinclair's coming-of-age thriller, a rapid fire story that secures him a safe berth in the pantheon of exciting, hard-hitting Tartan Noir authors.' ”
