But in Cuba, on the other side of the earth, nuclear tensions are at breaking point. The end of the whole world could be just days away. At the heart of it all is 14-year-old Laura Mann.

And Laura's about to discover that her own life is at stake - in ways she could never have imagined ...'Strong imagination and a capacity for awe abound in the work of Stephen Baxter.'
