Embroidery artist Mei Lin Chen discovers beauty and danger woven together when her students begin dying after completing patterns from a vintage 1920s needlework book. Each intricate design conceals coded messages about Chinese Paper Sons immigration fraud—forged documents that built one prominent family's American dream. As a Senate campaign brings unwanted scrutiny, someone is systematically eliminating anyone who might stitch together the truth. Mei must decode the deadly patterns, protect her surviving students, and uncover which family secret is worth killing for before she becomes the final victim. Can she untangle seventy years of hidden history before the last thread is cut?
