Pascual Rose has been living quietly in the shadows, trying to stay off the radar of his unsavory former employers. But some Russians have a score to settle with him; they want Nela, a rogue hacker who is trying their networks in knots, who was last seen in Pascual's company.

A man with loved ones is a man with vulnerabilities, and when the Russians kidnap his wife Sara, Pascual knows he has no choice but to betray Nela. The conflict pits spies against gangsters, and ranges from Barcelona to the Balearics, Marseille to Crete. SIMYA is a maze of Mediterranean intrigue, with no honor-or mercy-among spies and thieves, current or retired.
