A renegade government and a terrorist cell have gained access to nuclear artillery shells that they intend to detonate in the Canary Islands to cause a massive landslip that will crash on the eastern seaboard. Only Charlie Dean and his team at Desk Three can help avert catastrophe.In the Canary Islands off the coast of Africa lies the volcanic island of La Palma. It has been reported that the possibility of an earthquake or volcanic eruption along the southern ridge of the island could cause a landslip of a vast block of rock, megatons in size, into the sea. The result would be a devastating tsunami across the Atlantic Ocean striking the U.S. East Coast with waves up to 1,000 feet high.Desk Three is tracing the theft of Russian nuclear artillery shells from a military storage bunker in Tajikistan. Dean and Desk Three track the shells to a Chinese cargo ship and, ultimately, to La Palma. An Islamic terror group plans to detonate these warheads deep within lava tubes and caves inside the Cumbre Vieja volcano on La Palma. The simultaneous detonation at different points along the rift may trigger the feared landslip.Dean and Lia carry out operations in China and the Canaries to stop the plan--a scheme that encompasses renegade political factions and powerful terrorist cells, and that highlights a highly controversial theory that has been gathering attention in headlines and in the scientific community. This is a thrilling installment of the Deep Black series, drawn from real-life headlines and depicting a story that's frighteningly close to reality.
