In a dark alleyway in an alternative Elizabethan London, Fang’s heart stops. Moments later, it magically restarts again. Confused, and a little disappointed, about the fact he is not dead, Fang discovers that he’s become another creature entirely: an immortal. The first of his kind. That is until he meets Lazare de Quitte-Beuf, a theatrical Frenchman with an annoying zest for life who is afflicted with the same condition. Thrown together by their desperation to reverse their curse, grumpy Fang and cheery Lazare are drawn into the dark, underground city of Deep London. But in a world where immortality is a new and coveted commodity, it’s not long before they attract the attention of the powerful and greedy. And when in grave danger, surely the worst thing they could do would be to fall in love, wouldn’t it?
