The Sol Federation Marine Corps vessel was sent to recover an ancient derelict from the farthest edge of the Sol system. What they found could spell the end of humanity. Days after escaping the derelict ship and Pluto's destruction, Black Company is pulled from stasis hours from only to discover the solar system has gone silent. Nearly empty on both ammunition and fuel reserves, taking refuge at the silent, apparently dead station is their only choice. When they arrive, they find they are far from alone, and humanity's future lies in their hands. Derelict: Trident, the suspenseful, action packed fourth and final installment of The Derelict Saga, reveals the AI conspiracy, the true threat the exo-solar creatures pose to humanity, and the emergence of true non-carbon sentient intelligence.
