the HANYANG KEEPER: a Historical Thriller of Rare Manuscripts, Family Duty, and Secret Kept Since Joseon Dynasty

Give this to the one who comes from the west carrying the fold. For eight months, Columbia University archivist Han Soo-Yeon has returned to a single photograph without understanding why: a stone wall in Gyeonggi Province, carved with forty-three lines of a script no scholar has identified - and, on the back, her great-grandfather's instruction, written for a stranger who hadn't been born yet. When synthetic biologist Yuki Tanaka arrives from Tokyo carrying exactly what the note describes, the Han Jae-won family papers finally begin to yield their purpose: a custodian lineage that has maintained a forty-two-thousand-year geological record through four centuries of war, occupation, and diaspora, without ever fully understanding what they were keeping. In the wall's forty-third line waits a coordinate the keeping chain has never been able to read - pointing somewhere the eastern branch of the network has never mapped. As Soo-Yeon and Yuki race to decode it, the western and eastern halves of a much larger design are about to meet for the first time. THE HANYANG KEEPER is Book Four of The Convergence Sequence - the novel where four centuries of careful, unexplained duty finally reveals what it was always for.
