Capsoul by Alex Krasnov
A start-up manipulator invites three immigrant scientists with unique skills and experience to work on a project aimed to control human consciousness. Flashbacks to their childhoods and early adulthoods allow the heroes to unveil stunning connections between mirrors, significant historic dates, and art masterpieces to design and build Capsoul, a device capable of separating the soul from the body. Haunted by memories of another person, Andrew Serov comes to understand that any mirror's surface is described by the number 1666, which represents a duality. He finds numerical coincidences related to this number in gems with mirror symmetry, the mirror-flipped halves of the human brain, and even the DNA's death code. 1666 is also Andrew's constant reminder about the Venetian mirror-his family's heirloom,-once owned by a Russian patriarch. The mirror duality of the Capsoul is a treacherous deception, but also the opportunity for Andrew to solve the great riddle of his own life. The company's owner, however, sees the new creation as something more significant. For him, the Capsoul is an ideal tool for attaining immortality.
