Killian Lone comes from a long line of gifted cooks stretching back to the 17th century, and he yearns to become a famous chef himself. When he starts an apprenticeship under Max Mann, the most famous chef in London, he looks set to continue the family tradition. But the reality of kitchen life is brutal. Even his fellow apprentice, Kathryn, who shows Killian uncharacteristic kindness, can't stop him being sucked into the vicious and debauched world of 1980s fine dining; and gradually he is forced to surrender his dream.

Then he discovers a dark family secret - the legacy of an ancestor who was burnt as a witch for creating food so delicious it was said to turn all who tasted it mad. Killian knows he can use this secret to achieve his ambitions and maybe, finally, to win Kathryn's affections. But is he willing to pay the price?
