When Sarah Edgewater’s ex-husband is murdered by a radical organisation hell-bent on protecting their assets, she turns to Dan Taylor – geologist, ex-soldier, and lost cause.

Together, they must unravel the research notes that Sarah’s ex-husband left behind to locate an explosive device which is circumnavigating the globe towards London – and time is running out.

In a fast-paced ecological thriller which spans the globe, from London to Brisbane and back via the Arctic Circle, Dan and Sarah aren’t just chasing the truth – they’re chasing a bomb which, if detonated, will change the future of alternative energy research and the centre of England’s capital forever.
