The Passenger unfolds the thrilling story of a salvage diver named Bobby Western, who, after a late-night dive to a sunken jet, finds himself enmeshed in a mysterious and dangerous situation. The jet crash site reveals nine bodies still strapped into their seats, but the tenth passenger, the pilot's flight bag, and the plane's black box are inexplicably missing. As Western is drawn deeper into the ensuing intrigue, he is haunted not only by those seeking answers but also by the specters of his own past, including the ghost of his father, the man behind the atomic bomb that devastated Hiroshima, and the memories of his sister, Alicia, whose presence continues to torment his soul.

In Stella Maris, set in 1972, we meet Alicia Western, a brilliant but troubled young woman. At twenty years old, she checks into a psychiatric facility with a diagnosis of paranoid schizophrenia, along with a bag containing forty thousand dollars. Alicia, a mathematics prodigy, refuses to discuss her brother Bobby. Instead, she delves into the nature of insanity, the universal human experience, and her own personal grief for a brother who is both lost and unattainable.

Together, The Passenger and Stella Maris paint a portrait of a brother and sister bound by tragedy, conspiracy, and a quest for a reconciliation that seems beyond their grasp.
