'Agatha Christie fans will love this ingenious thriller...the pace is fast and furious and the twists satisfying' Good Housekeeping

Snow is falling in the exclusive alpine ski resort of Saint Antoine

The shareholders and directors of Snoop, the hottest new music app, gather for a make or break corporate retreat to decide the future of the company. At stake is a billion-dollar dot com buyout that could make them all millionaires, or leave some of them out in the cold.

The clock is ticking on the offer, and with the group irrevocably split, tensions are running high. When an avalanche cuts the chalet off from help, and one board member goes missing in the snow, the group is forced to ask - would someone resort to murder, to get what they want?
