The first novel in a new series by Andy McNab, about a former SAS soldier turned cryptography and cyber-weapons specialist. After leaving the SAS, Nathan Pike went rogue, selling his services to the highest bidder - a mercenary and amoral business, but increasingly lucrative and in demand.

In the dark world of cryptocurrency, there's a high price to pay . . .

From the central bank of El Salvador to a tantalum mine in Rwanda, the Acropolis Museum in Athens to the biggest freeport on the planet in Dubai, enter a world ruled by ones and zeroes and inhabited by people who don't believe in trust.

Nathan Pike is one of those people. To some he's a digital Robin Hood. To others he's nothing but an amoral hacker. A codebreaking and encryption expert, he sells his skills to whoever can pay him what he wants or give him something he needs.

And when he's sprung from a Cambodian prison by a woman calling herself Melody Jones, he's made an offer the likes of which he's never seen before.
