Coin

When her latest assignment for SIA goes wrong, Finn runs afoul of the feds. To avoid prison, she must take on a job too dirty for the US government: bringing down a cybercurrency used by terrorists and criminals to secretly send money around the world.

The cybercurrency is already under attack. A hacker has threatened to make its source code public unless the company founder pays a $10 million ransom. The agency hired to neutralize this threat? SIA.

Finn's mission: prevent the attack on the cybercurrency while shutting it down herself, all without the client's knowledge or destroying SIA's reputation.

More than money is at stake when the job takes Finn from historic Barcelona to a remote village in the Pyrenees, where she races to rescue an innocent. But will she be able to save herself from the feds?
