Publisher's summary
From Torchwood star John Barrowman, and Carole Barrowman, an epic thriller that finds Captain Jack and Gwen in a race to save humanity itself.

It starts with a series of unexplained events. Earth tremors across the globe. Women being driven insane by their heightened and scrambled senses. And the world is starting to notice – the number one Twitter trend is #realfemmefatales.

Governments and scientists are bewildered and silent. The world needs Torchwood, but there's not much of Torchwood left.

Captain Jack has tracked the problem to its source: a village in Peru, where he's uncovered evidence of alien involvement. In Cardiff, Gwen Cooper has discovered something alien and somehow connected to Jack. If the world is to be restored, she has to warn him – but she's quickly becoming a victim of the madness too...
