Atomic Coffin

In December 1984, SIS operative Heidi Sperling, also known by her codename Thistle, manages a daring escape from East Berlin. In her possession is the only copy of a crucial naval log, containing a message from a previously unknown Soviet submarine. Astonishingly, this submarine, identified as TK-15, has remained unnoticed and stationary between Scotland and Iceland for three years. The latest chilling communique simply states: ACTIVE. Heidi becomes part of a covert mission aboard the Royal Navy’s submarine, HMS Viking, which is tasked with locating and neutralizing TK-15 at all costs. The mission takes a perilous turn when Heidi’s sole ally on the submarine falls ill, revealing that the Viking is embroiled in more than just a Cold War chess move for nuclear superiority. Deep in the ominous expanse of the North Atlantic, a sinister presence seems to be awakening—one that no global power can contain.As the line between reality and hallucination blurs for Heidi, an inexplicable force obliterates the Viking’s defenses, driving the crew to the brink of insanity. Isolated in the abyss, Heidi must devise a plan to rescue the surviving crew members and neutralize TK-15 before it destroys what remains of her sanity.
